Hi, I was placed in a removal proceeding years ago before I became a Canadian citizen, and left the US (about 8 years ago) before they made a final decision on it (it was an abandoned asylum claim). I came to know later that I was under 10 year ban, so the ban would technically be over in 2 years; I decided to apply for I-212 waiver after I became a Canadian citizen (I didn't need I-192 since I never accumulated unlawful presence over 360 days and I do not have criminal record, so the waiver is purely for removal), and it was granted just two weeks ago (I applied early March 2018, submitted a bunch of documents, personal statement and and got fingerprinted). I went to Niagara Falls, NY over this last weekend, and after some processing (they were initially confused because they didn't see a lot of I-212, since), they let me in. But what's surprising for me was the fact that they were only asking some simple questions in secondary (like when I left, my citizenship, my job, how much money I'm carrying, etc), and they just let me in without fingerprinting, nor was I given a stamp or I-94. Is this normal? Are Canadian citizens typically just let in through land border without any stamping or paper I-94? How do they keep track of my departure? When I asked, they told me I didn't need it, but reminded me to always show the waiver every time I tried to gain entry. When I checked my I-94 record only, it said record not found. My arrival was recorded, but my departure was not recorded (I left Niagara, NY back to Niagara, ON on the same day). Thanks a lot.
