I traveled here over 40 times before I immigrated (DH is American and we did long-distance for 4.5 years). If you think you’ve got it bad as tourists, it’s even worse when you are married to a US citizen as statistically this is the demographic most likely to overstay. I was taken to secondary, they called my employer, wanted to check my bank account, had to put all my money on the table to be counted, questioned about our relationship. Awful.
Now that I live here and have a green card it’s much nicer. When I come home I get “welcome home! How was your trip?” Of course US citizens and GC holders go through first. It’s our tax dollars that keep them there.
To the PP who said “I’m a 42-year-old teacher and mother of 2, hardly likely to be an illegal immigrant”...you’d be surprised at the demographics of the illegal immigrants here. That’s why CBP can never assume anything.
