First I'll say that I say this as my view as a Brazilian, that actually have a very good and default opinion about the U.S, as far as a Brazilian can be.
U.S is an economic powerhouse, Russia isn't. So yes, U.S attracts worldwide immigration. And of course, who goes to the U.S, already go there because... like it. If they didn't liked it, they wouldn't go.
But Latin America population is almost 700 million. Those who go to the U.S are a small minority, and specially from countries that are very much, to be kind, not going well, so they see the U.S as an example to be followed, like the Cubans and Venezuelans in the U.S.
But Latin America isn't only them.
I suggest checking some polls on the subject on China/US, and you'll see majority of latin americans have positive opinion about China¹, with numbers actually similar in some countries to the U.S. While 16% have positive opinions about China in the U.S, it's 61% in Chile.
And of course, I'm not even considering the governments here, which I think should be the main point, as they are the one who will drive the countries relations.Most Latin America governments, see the U.S as a country that would never let another economic world power rise in the Americas continent. Majority of Brazilians believe that Brazil should reduce use of Dollar², and Trump made specific threats to countries that try to avoid dollar.
This view is actually very widespread, but is worse between leftists, the leftists in most part of Latin America are more what we call "Anti-american", because of U.S Operation Condor that imposed right-wing dictatorships in the region. And it goes even newer, as Brazilian former President's Dilma Rousseff was spied back during Obama terms. That was discovered in 2013 or so.
The whole Trump U.S thing in Panama it's because of the growing influence China was getting there, too.
