In 2014, I worked on a cruise under a C1D visa, which was valid for 5 years. However, I resigned early from the cruise line, which made me have a parole stamp on my passport saying "DT Removed Under Safeguard."
This year, I'm traveling to the UK (I had been there a couple of times before the cruise job). There is a question on the visa application form that says "Have you ever been deported/removed from other countries beside the UK?" I have no idea if I have to answer Yes or No.
On my passport was stamped Removed Under Safeguard but I actually resigned from the job and willingly left the US. I didn't ever stay after the given visa conditions. I still have the evaluation paper that said I resigned from the cruise job.
