I arrived in the US on a CR1 visa yesterday. I did not realize it at the time, but the Washington (IAD) CBP officer did not stamp my visa nor my passport. The stamp was supposed to endorse the visa. Doesn't that mean I don't have a temporary I-551 of one year like it says at the bottom of the visa? I asked the officer to change my mailing address. USCIS' Emma confirmed that the address change went through and that my green card is being processed, but could not tell me if I am a Lawful Permanent Resident and that I should ask an immigration lawyer. Emma further asked if I wanted an appointment to get a stamp. I said yes. However, that can take up to 30 days, apparently? Can I do anything at all without an I-551? I wanted to apply for jobs, and have interviews lined up, but I'm not even sure if I can do that now.
