Either in regards to the current political situation, or for other reasons. What drew you to the idea of living in another country? Do you think whatever benefits it offers are really worth it, or is the grass just greener on the other side of the fence?
As a former undocumented immigrant, you too are thinking inside the box, when the time comes, legally immigrating is the least of your concerns.
Immigration destination countries will generally close their borders long before they’ll start kicking their legal immigrants out en masse.
But what I was actually getting at was that at some point, the USA will probably start making it really difficult to physically leave the country. It’s the difference between going somewhere with some amount of wealth by plane or car and trying to flee on foot over a green border while being hunted by the border police.
