Very interesting indeed. I guess I shouldn't be too concerned about signatures, then.
Now, I do want to ask a few questions regarding these specific records:
For the Social Security card and the mailer it came in, do you know if that letter has some of sort generic title / name to it? If so, can you please share?
I'm trying to see if I can FOIA / PA that. Reason being that I have two SSN cards throughout my life - The first one has the "NOT VALID FOR EMPLOYMENT" notice on top, while the other one does not. I logged into my ssa.gov account, and noticed that I don't get the notice that says that the SSA has me in their records as someone who is not a U.S. Citizen. Afterwards, I checked with my parents who said that they THINK that they might have also updated my status with the SSA as soon as I got my first U.S. passport. If there is evidence of action done by my parents on behalf of me via the SSA, then perhaps that could be good evidence of actual physical custody.
However, from what I heard, the SSA does not really like FOIA / PA requests that are "all records" requests. So, I'd want to figure out what I'd want to ask them for.
For the "tax transcript" part, forgive my ignorance, but what's exactly the difference between a tax transcript and IRS 1040 form? I know that the IRS 1040 sort of serves as a "cover page" for tax return filings, which includes many additional forms that are supplemented to it. But what exactly is a tax transcript? Which one is better for this purpose?
I do have a U.S. passport, and my very first one was issued only shortly after both my parents became U.S. citizens. Several, in fact throughout the years. And in fact, the point that people were making about how it has "the same evidence" resonated with me, until I realized that when I got my first U.S. passport around 20 years ago, the DOS had a completely different interpretation of the "physical custody" portion of INA Section 320. Back in those days, they had interpreted it as where the child is physically with the parent at the acceptance facility when submitting the passport application. When I realized that this was the case, I was crushed, since I was hoping that I could FOIA / PA past passport applications.
I actually wonder if an approved DS-11 application can serve as proof of physical custody for USCIS Form N-600, if I could FOIA / PA it. If you think about it, it has a lot of info about the parents' and child and we they all live and also a date for when the application was signed and submitted.
Other than that, I was able to get a bunch of medical and school records, but they weren't always quite during the exact year that my parent became a US citizen, though, they were still from when I was a minor.
