My wife's green card application is on hold, waiting on my I-864 (US taxes.. bah! Don't open a Limited in the UK if you're a US citizen unless you're ok with paying $1200 to have your personal US taxes done).
We have done the interview portion at the London embassy already. They handed back the x-ray in an envelope. That envelope had a handwritten 'exp. {date}` on it.
We're concerned that we will have to enter the US before that date.
Thus: Does the x-ray expire once the embassy has reviewed and approved the immigrant visa. If so, what happens? Do we "just" need to get another medical? Or does the whole process start over - medical, interview, resubmit forms, new legal clearance etc.
Answers from personal experience would be great - actual references to legal code would be absolutely fantastic.
