I submitted my app to Radex but they want a new FBI background check because I have traveled to the US for short trips since the date of the FBI background check. It would likely take months to get a new FBI background check, even assuming I can get my fingerprints taken somewhere in this tiny pueblo. So I may just go back to the US without completing the process (yet again). Thing is, I will have overstayed my visa by a significant amount. I recall reading posts where someone who overstayed their tourist visa was forced to sign something and then banned from re-entry. Is that the most likely scenario?
