In the mid 2000s, I had to leave the US for renewal while leaving all my hard assets behind. I had a plan in place in case I couldn't go back to the country, which did happen to some people. These people had their interviews, but they got held back outside the US, sometimes for months, waiting for the renewal process to finish. I had an immediate renewal, but was almost held back for some red tape reasons.

This sucks but it isn't new, unfortunately.
