I recently married but it was not easy to do so because I was born in the US as the gov here didn't like my birth certificate (missing an "apostille") and I needed a document from the US that they couldn't give me in time (or at all because they said I need to be there in person but they're not open for in person visits) because of Corona.
I ended up finding a loop hole meant for war survivors that can't get a hold of documents which allowed me to marry my Austrian wife without the apostille.
Didn't get easier though because all shared banking accounts we have, she has to report to the IRS too, we both have to sign a waiver to be excempt from banking confidentiality and I have to send them my tax papers every year despite never having earned a single dime in the US any paying full taxes herein Austria.
Also Austrian banks and even European trading sites won't give me access to the stock market (they just say you were born in the US, we can't let you trade stocks over their platforms) but I don't have an address in the US so I can't do it on an US site either.
This article gives me less hope of fixing these things in the future
