Hello,
thank you for your exhaustive response.
My category is research scholar, professor and I was subject to the 212e because I received gov funding from my home country. The rule has been waived through NO Obj statement from my home government and I have already received all the documents from USCIS stating a favorable approval (the free document with lady liberty where it’s written on top action notification).
I would like just to do a clean transition from J1 to H1B next year and finally to GC since I have also already received an approved I140. In my case I made it sure that no new DS will be created and I’ll keep the actual one valid until it’s normal expiration next year, in order to not create issues with the waiver approval.
I hope that not changing the DS, even if I have to do research for some time in a second place, does not compromise my status.
best,
