Okay so I have a warrant in canada for assaut I missed court because I moved back to the usa , but I'm a green card holder of the USA do you thinkk I could Fly to the Caribbean from the USA , or will my warrant show up in the data base ?

What exactly is your citizenship; if you are a green card holder working in the US, you are from somewhere else and allowed to work in the US.

If you are charged with assault and bolted from another counrtry, then you will be flagged no matter where you try to cross.

You can't just 'miss court' and move to another country; and go scott free.

Tick

Yes it will show up, and it will effect your green card status
