Hi there,
I have a complicated situation. My visa stamp is valid until Dec of 2016, and I went back to visit family in Oct of 2016, so theoretically I did not have to renew my visa, since it is still valid. However, I decided to renew my visa anyway while I was home, since I thought I might need to go for a business trip in another country next year and have to re-enter the US. The problem is this time my visa got administrative processing and I had been waiting for a month and did not hear back. My question is: can I ask for my passport back from the consular and just try to enter the US, since the previous visa stamp is still valid? Thank you for the help!
