香港からアメリカへの移住

ビザ取得経路

Hong Kong residents need a visa to enter the United States. Hong Kong is not part of the Visa Waiver Program ^[1].

Chargeability Advantage.

For immigrant visa purposes, Hong Kong-born applicants are charged separately from mainland China ^[2]. This is significant because mainland China-born applicants face severe multi-year backlogs in employment-based categories, while Hong Kong-born applicants often have current or near-current priority dates. If you were born in Hong Kong, you benefit from shorter wait times for green cards. If you were born in mainland China but reside in Hong Kong, your chargeability is based on birthplace, not current residence.

H-1B Specialty Occupation.

The H-1B is the primary work visa for Hong Kong professionals with at least a bachelor's degree in a specialty field ^[3]. The employer files a petition with USCIS, and the visa is subject to an annual cap with a lottery selection process. H-1B allows dual intent, meaning you can pursue a green card while on H-1B status ^[3].

L-1 Intracompany Transferee.

Hong Kong residents who have worked for a multinational company for at least one continuous year can transfer to a US office in a managerial, executive, or specialized knowledge role ^[3]. Given Hong Kong's role as a financial and business hub, L-1 transfers are a common pathway for professionals in banking, consulting, and technology ^[3].

O-1 Extraordinary Ability.

For Hong Kong residents with demonstrated extraordinary ability in sciences, arts, education, business, or athletics ^[3]. No annual cap applies.

Employment-Based Green Cards.

Hong Kong-born applicants can pursue EB-1, EB-2, EB-3, and EB-5 immigrant visas with processing times that are generally more favorable than those for mainland China-born applicants ^[4]. The EB-5 investor program requires a qualifying investment in a US commercial enterprise ^[3].

No E-2 Treaty.

Hong Kong does not have a bilateral investment treaty with the US that qualifies its residents for E-2 Treaty Investor visas ^[1].

Family-Based Immigration.

US citizens and lawful permanent residents can petition for Hong Kong family members through the I-130 process ^[4]. Wait times depend on the relationship category and the monthly Visa Bulletin.

F-1 Student Pathway.

Many Hong Kong residents enter the US on F-1 student visas for undergraduate or graduate study, then transition to work status through Optional Practical Training (OPT) and employer-sponsored H-1B petitions ^[3]. US universities are a well-established pipeline for Hong Kong students.

米国税務義務

Once you become a US tax resident, the IRS taxes you on worldwide income. Tax residency is determined by the green card test or the substantial presence test ^[1].

No US-Hong Kong Tax Treaty.

The United States does not have a bilateral income tax treaty with Hong Kong ^[2]. Hong Kong operates a territorial tax system, taxing only income sourced within Hong Kong. Once you move to the US and become a US tax resident, the US will tax your worldwide income, including any Hong Kong-source income. Without a treaty, there is no bilateral framework for reduced withholding rates, though the US foreign tax credit (Form 1116) provides relief for Hong Kong taxes paid ^[3].

Hong Kong's Territorial System.

Hong Kong does not tax income earned outside its borders. Once you leave Hong Kong and cease to have Hong Kong-source income, your Hong Kong tax obligations generally end. This creates a relatively clean tax departure compared to countries that tax citizens on worldwide income.

Substantial Presence Test.

Hong Kong residents on US work visas (H-1B, L-1) typically meet the substantial presence test, requiring at least 31 days in the current year and 183 days over a three-year weighted period ^[1]. F-1 students are exempt from the day count for a defined number of years ^[1].

FBAR and FATCA.

If you maintain Hong Kong bank accounts (common given Hong Kong's role as a financial center), FBAR reporting is required when aggregate foreign account balances exceed $10,000 ^[4]. FATCA Form 8938 applies to foreign financial assets above higher thresholds ^[5]. Hong Kong financial institutions report under FATCA through the intergovernmental agreement framework ^[5].

No Totalization Agreement.

The US and Hong Kong do not have a Social Security Totalization Agreement ^[6]. MPF contributions and US Social Security contributions are entirely separate systems ^[6]. You must meet US work credit requirements independently through US employment.

Investment Income.

Hong Kong does not tax capital gains or dividends. If you have Hong Kong-based investments, the transition to US residency means these gains become taxable under the US system. Consider the timing of asset sales relative to your move to minimize unnecessary tax exposure. Consult a cross-border tax advisor before establishing US tax residency.

医療と保険

The US does not have a universal public healthcare system. Coverage depends on employment, immigration status, and state of residence.

Employer-Sponsored Insurance.

Most Hong Kong residents arriving on work visas receive health insurance through their employer. Plans typically include medical, dental, and vision coverage. The employer subsidizes a portion of the premium, with the employee paying the remainder through payroll deductions.

ACA Marketplace.

If your employer does not offer insurance, purchase a plan through healthcare.gov during open enrollment or within 60 days of arriving (qualifying life event). Premium subsidies are available based on income.

Comparing to Hong Kong's System.

Hong Kong's public healthcare system provides heavily subsidized care through the Hospital Authority. The US system operates differently: care is delivered by private providers, costs are substantially higher, and out-of-pocket expenses (deductibles, copays, coinsurance) are standard even with insurance. Budget for healthcare costs that will be significantly higher than what you paid in Hong Kong.

Medicaid.

Lawful permanent residents face a five-year waiting period for Medicaid eligibility in most states. Nonimmigrant visa holders generally do not qualify.

Prescription Drugs.

US prescription drug costs are higher than in Hong Kong. Medications available at Hong Kong pharmacies may have different brand names or require a US prescription. Bring documentation of current medications with generic names (International Nonproprietary Names) and dosages.

Mental Health.

Mental health services are covered under most employer and marketplace plans. Cantonese-speaking and Mandarin-speaking therapists are available in metro areas with large Chinese-speaking populations (New York, San Francisco, Los Angeles) and through telehealth platforms.

銀行と財務計画

Opening a US Bank Account.

You can open an account at major US banks with your HKSAR passport (or BNO passport), visa, and a US address ^[1]. Some banks require a Social Security Number; others allow you to open with a passport and add the SSN later. Apply for your SSN promptly after arrival if your visa authorizes employment.

Credit History.

Hong Kong credit history does not transfer to the US. You start with no US credit score. Secured credit cards are the standard starting point. HSBC and Citibank, both of which operate in Hong Kong and the US, may offer global relationship benefits that make initial account opening easier, though credit-building still requires US activity.

Maintaining Hong Kong Accounts.

Hong Kong's banking infrastructure is robust, and many residents maintain accounts after relocating. FBAR and FATCA reporting obligations apply once you become a US tax resident ^[2]. Hong Kong banks may request updated tax residency information under the Common Reporting Standard.

MPF (Mandatory Provident Fund).

Your MPF balance remains in Hong Kong after you leave. You may be eligible to withdraw it under certain conditions (permanent departure from Hong Kong). Withdrawn amounts may be taxable in the US as foreign pension income. Consult a cross-border tax advisor before making withdrawal decisions.

Remittances and Transfers.

Moving money between Hong Kong and the US is straightforward given Hong Kong's open financial system. Services like Wise and OFX offer competitive exchange rates for HKD-to-USD transfers. HSBC Global Transfers allow fee-free transfers between your HSBC accounts in both jurisdictions.

Investment Accounts.

If you hold Hong Kong investment accounts, the transition to US tax residency changes the tax treatment of capital gains and dividends (Hong Kong does not tax these; the US does). Consider restructuring your portfolio before establishing US tax residency. US-based brokerage accounts (Fidelity, Charles Schwab, Interactive Brokers) accept permanent residents and work visa holders.

Cost of Living.

The cost of living in most US cities is lower than in Hong Kong for housing (outside Manhattan and San Francisco), but higher for healthcare and transportation. The specific metro area matters enormously.

引っ越しの物流

Shipping Household Goods.

A container from Hong Kong to a US West Coast port typically takes 2 to 4 weeks by sea. East Coast delivery adds 1 to 2 weeks. Hong Kong has excellent international shipping infrastructure, and multiple freight companies handle residential relocations. Get at least three quotes for door-to-door service.

US Customs.

Personal effects and household goods imported by immigrants are generally duty-free if owned and used before arrival. New items may be subject to duties. Restricted items include certain foods and agricultural products. Electronics (voltage differences: Hong Kong uses 220V, the US uses 120V) may require adapters or replacement.

Flights.

Direct flights from Hong Kong International Airport (HKG) to multiple US cities are available on Cathay Pacific, United, and other carriers. Flight time is 12 to 16 hours depending on the US destination. Los Angeles, San Francisco, New York (JFK/EWR), and Chicago have the most frequent direct connections.

Driving.

Hong Kong residents with a full Hong Kong driving license can drive temporarily in most US states. You will need a US state license within 30 to 90 days of establishing residency (varies by state). Hong Kong drives on the left; the US drives on the right. Written and road tests are required.

Pet Import.

Dogs and cats entering the US from Hong Kong must meet CDC and USDA requirements including proof of rabies vaccination. Check the current CDC rabies risk classification for Hong Kong and any state-specific requirements at your US destination.

Voltage and Electronics.

Hong Kong uses 220V/50Hz electrical systems. The US uses 120V/60Hz. Most modern electronics (laptops, phone chargers) handle both voltages with a plug adapter. Appliances with motors or heating elements (hair dryers, rice cookers, electric kettles) generally need to be replaced with US-voltage models.

文化的適応

Chinese-American Communities.

The largest Chinese-speaking populations in the US are in the San Francisco Bay Area, New York City, Los Angeles, and Houston. These communities include substantial Cantonese-speaking populations with deep roots, particularly in San Francisco's and New York's Chinatowns. Cantonese is widely spoken in these areas, and Cantonese-language media, restaurants, and cultural organizations are well-established.

Workplace Culture.

American workplaces tend to be more direct and less hierarchical than typical Hong Kong corporate environments. Individual initiative and speaking up in meetings are valued. The pace of decision-making varies by industry; finance and tech tend to be fast-paced in ways that feel familiar to Hong Kong professionals.

Language.

Most Hong Kong residents have strong English proficiency from Hong Kong's bilingual education system. American English differs from the British English conventions used in Hong Kong (spelling, vocabulary, pronunciation), but the adjustment is usually minor. Cantonese is useful for community connections but English is the primary language of professional life.

Social Norms.

Tipping is expected at restaurants (15 to 20 percent), for hairdressers, and for taxi/rideshare drivers. Personal space expectations are larger than in Hong Kong's dense urban environment. Queuing culture exists but is less orderly than in Hong Kong in many contexts.

Housing.

US housing is generally much larger than Hong Kong apartments. Expect significantly more space per person, even in expensive US cities. Renting typically requires a credit check, which is challenging for newcomers without US credit history. Some landlords accept additional security deposits or a co-signer in lieu of credit history.

Driving Dependency.

Most US cities outside New York require a car for daily life. Public transit options vary dramatically by city. Hong Kong residents accustomed to the MTR and extensive bus network should factor in the cost of purchasing, insuring, and maintaining a vehicle in the US.
