infopass appointment.
I know that anyone should have infopass to visit local INS office. But I got an emergency, I have to travel to Canada tomorrow. So I got up really early this morning and went to our local office. The officer gave me the last 5th ticket. But I had to wait till most of the infopass persons finished their stuff. I was the last one who stepped out the office.
The officer was really nice to me. And I got my passport stamped. I don't need to wait till my real GC comes.
So, if you really have an emergency, go there really early. They might do it for you.
