Now they want me to go through the Photo ID process, but I don't have a US drivers license, only a permanent resident (green) card for ID. Which should be fine, after all it works as ID for literally everything else I could need ID for in the US - including flying. Support have been fairly responsive, but they keep sending me back to through their photo verification process, and I keep telling them "but this is not a driver's license, please look at the pictures!".
It's really annoying - this is a federally-issued photo ID I'm required to carry with me, and yet Coinbase seems to be struggling to accept it. In the meantime my money is stuck and I don't know how to get it back.
