Most countries in Latin America require you to be a citizen of that country. Some countries, such as Chile, have hired foreigners but even with a family member with very high connections at LATAM, I couldn’t get an interview.
Copa has hired foreigners with 1000 hours total time minimum.
Belize “hires” foreign pilots but it’s mostly pay to fly.
Your best bet is to stay in the US. You could go to a US territory such as flying for Star Marianas or going to Puerto Rico or USVI, if you’re looking for an overseas type of experience.
