I agree with everyone else: try to get your old job back. Throw away the 'it will look ridiculous' idea - none of this will matter in a couple of months.

If they were disappointed to see you go, they will welcome your return.

As another person who has had a similar experience before, and whose immigration status is tied to employment, I can imagine how distressing this must be[1]. I hope the general outpouring of support on HN eases your mind a bit! Think it through clearly and move on.

1: In fact, I'm pretty much in the same situation as you were: accepted an offer with a bay area company and undergoing the visa process, and this post does give me pause. I'll respect your decision to not name names though.
