LATAM Views on Immigration: Venezuelans --> Colombia?

With all the talk of regime change in Venezuela recently, I thought I'd take a look at emigration desire within country and immigration receptiveness across LATAM where folks are likely to go.

Atlas Intel published their LATAM Pulse for the month of October covering a wide range of issues, with immigration featuring prominently. This slide seems to indicate if Venezuelans were to leave, they're likely to find more hospitable hosts in Argentina and Brazil compared to other neighbors.

Then comes the question of how many would leave in the case of regime change, war, or general increased instability?

According to a UN report last year, 1 in 4 Venezuelans have already left the country, and multiple polls report large emigration desire, including up to 40% of those under the age of 30. On the low end of estimates we're looking at 1MM exits, with potential to reach well into 3.7-4MM territory if things change for the worse over the coming months.

I'd expect in this scenario an increase in anti-immigration protests and more restrictive laws especially in Colombia which is likely to receive the brunt of the initial exodus (proximity + large existing diaspora population) combined with high negative sentiment around immigration.

Of course, if the situation stabilizes, I'd expect positive inflows back to the country from the diaspora as is happening now in Syria.
