I understand that but the TM30 submission is a report of when you are there dates etc so I am curious as to why they would accept the Yellow Book as a substitute for that. That’s why I wondered if you had ever used it for 90 day report purposes before. Have you? I am interested to know because if having a yellow book means that you don’t have to submit a TM30 it would make it a much more useful document. I wonder how immigration would know that you have one when you do online 90 day reports unless the district office system is connected to the immigration system.
