We filed for DCF (spouse of US citizen) in 2009 at Abu Dhabi Embassy. In those days DCF was more broadly permitted and the A-Z timeframe could be a month or less if all went well. In our case it didn't.
The visa officer told us that she had determined that the marriage was bonafide (means I-130 was approved?) However, she issued a 221g requesting further evidence of US domicile of petitioner.
Thereafter, we failed to pursue the application and I understand that it was eventually terminated by the Embassy due to inaction.
I guess I need a lawyerly answer as to whether there is any legal basis or procedure to reopen that case, instead of filing a new petition with USCIS. I realize the answer is probably negative but wish to exhaust this option in case there is any basis out there.
