All,
I am in a situation where marriage is breaking ..despite best efforts from my side ..Married 4 years .. in relationship for 6 years .. We both moved from state A a month before the joint filing. Once we moved here everything is going down in our relationship.I had my fingerprints done and she moved to state B to her parents and I am in state C from where we filed jointly.
Now she refuses to come back I am not playing blame game but there are things which cannot be worked out between us.
I know a divorce or filing for it can be useful in changing my joint filing to divorce based waiver .. but both states B and C have residency requirements which we dont meet if divorce is the last resort .
Looking at the I 751 cases recently mine can be decided very soon. There is no lack of evidence infact three boxes full ..4 years worth.
My question is what happens if I 751 is approved while we are physically separated and working on our marriage through counseling or adjusting ..What are the consequences ..
Please do not judge me .. Nobody will live in a 6 year relationship playing games ..

Anyone !! experts moderators ? maybe if I add a question hypothetically if my gc is approved do i have to apply for I 751 waiver after we divorce or do i inform USCIS the state of our marriage now and wait ? It will take atleast 4 months before anyone of us can file in either state ..so my question

Have you been married for 4 full years? When was your I-751 filed?

Married for 4 years yes .. I 751 filed three months back ..Biometrics done about 4 weeks back ..My initial GC was approved only two weeks before my 2 year marriage anniversary ..
