It looks like both parties are using the same account to post questions and responses, I think that's where the confusion is coming from.

Thanks, so after filing it, is there a way to know if it will go back to Nebraska or if it will go to some other service center, or it's just luck of the draw on where they get sent after the lockbox office sends them off?

I received an approved I-130 for my wife, couple of months went by with no response from NVC, I looked back on my NoA2 and seen verbiage about filing an I-824, googled this and found it's an application for action on an approved I-130. Looked at my copy of my submitted I-130 and realized I left the country blank on question 62.a Called USCIS and was told to make a change to an approved petition that's leaving the U.S requires an I-824. So after all this I have a couple questions. There are questions on the I-824 that I'm not exactly sure what is the correct response. I'll attach a picture of the I-824 question. I'm thinking it's either 1.b or 1.d, there just is not any other questions on the I-824 for how they would know which embassy to send my petition to, unless they just go off her geographic information from address etc. Second question is, am I able to tell when I file my I-824, where it will go? My NoA1 had an address of Nebraska on the bottom, my NoA2 had an address of National Benefits Center in Kansas. The reason I'm asking is because Nebraska has a current processing time of 22-23 months for an I-824, NBC is 5 months. Our receipt number starts with IOE. If my NoA2 was sent from NBC in KS, could that be where my I-824 goes, or since it's mailed to the Phoenix lockbox, it could be sent to Nebraska? Or is there a chance that it could go to any service center in the U.S? I'm in the upper midwest of the U.S geographically. I'm already planning on going back in a few months to visit my wife, so if it goes to Nebraska, I was considering just a withdrawl of the current CR-1 and refiling a new CR-1 once I return, as 15 months at Nebraska vs 23 months is a long time. Once an I-824 is submitted, is the CR-1 still able to be withdrawn if the processing time is 2 years vs a year and a half?

Thanks, appreciate it.

So, reading that, I will need to file by mail and still fill out a W7?

I tried searching for ITIN here, but some stuff was old and a little confusing. I tried filing my taxes online, but it asks for a SSN or drivers license number. I went to HR Block and the person said to get something called ITIN or PTIN. Is this required to file married but seperate? Some of the searches said an ITIN took over a year to receive. I am wanting my taxes filed and complete so I have them ready when she gets her CR1 interview. I know I can't file single now, even though she is not in the U.S yet, would it be in our benefit to get the ITIN/PTIN? Or is there a way to file married and not have one and just file regularly when she does arrive here?
