You travel to (A) country to work in a Government sponsored program.
The Government decides to kick you out of the program and send you home because you speak out against the government.
This is a violation of the first amendment but because you are not a full citizen of the country you are traveling to work in, the sponsor of your program can decide you don't qualify to stay for ANY reason. That is work or student sponsorship in the #unitedstates.
