Passport question..

So I have an appointment to get my correct passport on 1/15 at my local post office and I've just had the thought....since it's self-selected for a gender marker change, and my application goes through, but Trump revokes the self-selection of gender markers, will my passport just, not be issued? It take 4-6 weeks to arrive, but I imagine that the acceptance of the forms is instantaneous in the system, so in the limbo period I just......wait??? What are peeps speculations? Please help a girl out!

(I'm also updating my name so who knows if that will be simple too. The joys of paperwork for being trans ¯\_(ツ)_/¯ )

Thanks :3
