Moving to another country will require you to have a way to support yourself.
Most countries will not allow you to work without a permit or without bringing in a good deal of money to invest in their economy. Some countries will give you a work permit if you are bringing in a particular desired skillset.
You cannot simply move and get a job. (in most cases.)
The best way to work / live overseas is;
1) Become an English teacher for a ESL program.
2) Have a steady source of unending income from the U.S. already (business, pension, etc.)
3) Have a good deal of money to start a business in new country.
4) Have a skillset the country is interested in so they sponsor you for immigration or temp/perm residency.
Getting an expedited passport is easy.
Another way to work / live overseas is to work for the Dept. of State or associated agencies like USAID. I have worked with the Dept. of State for many years. There are jobs one can do that are "non-professional" (called Civil Service or Foreign Service Specialist jobs) which pay a salary (not significant usually - but they also provide housing.) One must have a clean background and a skillset they need.
The down side is that you will not be able to choose your country of assignment. You could end up anywhere...usually for three year assignments before transfer.https://careers.state.gov/work/opportunities/available-jobs
