Hello. I've received NOA2 on the I-130 that I submitted directly to London USCIS. Since then, we've moved to another flat in the same county. I know that in the US, there's definitely a form to fill out for address change. But is there something similar when you're dealing with the London embassy and USCIS overseas? My husband hasn't done his DS-230 yet though, so would he be able to just use the new address on it and that would be notification enough?
I had to change our delivery address to my office between the NOA1 and NOA2 as our post was being stolen (incuding our NOA1!). I did this before I even knew of VJ, so I thought the best thing to do was call the Embassy Extortion Line. They told me to email the londonconsular email address, gave me the super-secret code, and to include all our various details (which in your case would include your case number -- you have P3 now, right?). This worked just fine -- got the standard blahblahdeletedblah reply back, and two days later came confirmation that the address had been changed, along with the equivalent of our NOA1.
Now, you ask whether just putting the new address on is enough. I would venture to say no, because someone in the UK forum (I'm having a senior moment, can't remember who it is) has been saying that they are still getting stuff posted to the wrong address. I'm not sure how they had notified the Embassy of the change, indeed if they notified the same way I did and still had the wrong result, but I'll tell you this worked for me. As this is VJ, I'm sure someone will disagree with me, but it might be worth stumping up for the code this time.
