US Immigration from Russia

Hello everyone,

My husband and I have had to move multiple times since living together in the US. We updated his address with Selective Service 2 times, but the last time we moved, we forgot to update the address. Therefore, we don't have the "Registration Acknowledgement" card/letter with the address at the previous place we lived. Is this going to be a problem? Do they ask to see all of the Selective Service registration letters, or just the most recent one?

Please let me know as now we're worried about it. It just completely slipped our minds last time we moved as it was a stressful time for us. I feel really bad about it. We will update our current address ASAP and hope that the new letter arrives in time for his interview.

Edit: I just realized on the website it says it could take up to 30 days to get the new registration. We also forgot to update when we moved to our current place. Thus, I'm not sure we will get the new registration card in time...has anyone ever been in this situation and was it a problem? Will we get an RFE?

To clarify: we are missing 1 address change registration and we no longer live there now, so that will be impossible to get. We forgot to update the current address where we are within the 10 days, we did it now but it says it can take 30 days to get it in the mail, so not sure it will arrive in time for the interview.

So I am about to send in the I-751 for my wife.

The question is: How long will it be to get the initial response that extends it for one year?

The next question is: The card expired already Mar 24 of last year. If it extends it for one year of the Mar 24 of last year, then it is going to expire in less than a month. So, what to expect to happen?

The reason this is important is that we are going to take a trip to Russia in June, and I need her greencard in order so that we have no issues when returning to the US.

It seems like I read that we could get an appointment and get the Card extended with a sticker.

I have a TD Ameritrade IRA which names my wife as the Primary Beneficiary.

However, I have not been able to find a way to document this except by taking a screenshot of the account. The monthly statements do not include this information.

Is a screenshot acceptable? Or maybe do the screenshot, and also provide the monthly statement?

Can someone confirm for me that this is the correct address to file a I-751:

USCIS
P.O. Box 21200
Phoenix, AZ 85036

I got that from here: https://www.uscis.gov/i-751-direct-filing-addresses

But that is different from what it says here:

Just want to make sure I don't make any mistakes.

One additional question: How long does it usually take to get the first response on the I751? We want to go to Russia in a new months to visit family and want to ensure we will have it by then for travel purposes.

Have any other wives of Russians (and/or other similar places) legally changed their names to the Russian traditional female form of the last name? Example - Pashkov/ Pashkova?

I am wanting to legally change my name, but unsure if I will be able to change it to that form or it will be the exact same as my husbands.

Thanks!
