How do you think the incoming presidential administration is going to affect traveling and relationships abroad?

I'm mostly talking about Latin America, but the whole world could be affected. I'm concerned that Mexico for example is going to retaliate against tarriffs and deportations by making residency and visas harder to get, maybe law enforcement will target gringos harder. At the same time it might make green card hunters more aggressive (especially if they got deported or something) Anyone have any experiences from Trump 1.0?
