I was put in a waiting area while the officer talked to my husband for probably twenty or thirty minutes and then was pulled up to the desk with him, yeah. He started asking me questions that he had probably already asked my husband to see if we had different answers, finally found something in his computer database or something I guess that agreed with what we were saying? and flipped a switch, was suuuuuper nice oh the US needs more engineers, you know how Canadians love to just hop over the border and stay and adjust status etc etc. My husband came over back in 2007. Officers have always been dicks and there has always been a weird, aggressive anti legal immigration undertone amongst an agency that is supposed to be supportive of legal immigration attempts. It's probably gotten worse but it's definitely been there for a while. 9/11 didn't help attitudes. It's usually fine, if a hassle and it can be scary in the moment because innocuous things can get twisted by people with a lot of power.
