Emergency situation:
H-1B visa, changing a job from A to B. got an oral offer after the on-site interview, but raised H-1B transfer question before official offer. Now B institution tends to change mind, not going to issue an official offer anymore because they have no such experience, don't know how to do it, and feel bothersome...
I was so stupid to bring this issue at wrong time.
What can I do now? Thanks for your advice!
