Once your file hits NVC is the time to request a consulate change. Some have done this and have been successful because the file is not moving till the embassy opens, so it gives you a chance to "catch" the file before it is sent.
Two factors you must take into consideration. First one is are you a resident of UAE for more than six months? Second, can you wait an additional 2-3 months that this transfer may take? Then.....
If your case file resides at on embassy and you want to transfer it from one Embassy to another U.S. Embassy/Consulate, you contact the appropriate U.S. Embassy/Consulate directly in the country where you wish to apply and submit Form DS-3098 for case transfer. Click here for the full list of all U.S. Embassies and Consulates overseas.
The old Embassy will need to receive a formal file transfer request from that U.S. Embassy/Consulate in the country where you wish to apply. Upon receipt of this request, they will immediately forward the file for the New Embassy to process. (Expect up to a 30+ day delay)
Once you contact your New Embassy you then can discuss the transfer of your fee if you have paid it prior to the decision of transferring your case to your new embassy. Be sure to have your payment receipt available.
If your case goes from embassy to embassy, then NO you don't get a new case number. The case number will begin with original alpha nomenclature i.e.. AAAXXXXXXXXXX. If her case comes from NVC then you will have a case number starting with the embassy that you will interview in. To make your payment using your old embassy's case number you establish your profile with that case number then you link your payment to your profile.
If your case has not arrived at NVC then wait till it does and that is where you make your request. It can be done by phone and you may be given follow-up instructions. Good luck and stay engaged.
