Me again, with another basic question!
I'm a British citizen. I'm currently in Canada on a working holiday visa, and will have legal status in Canada until early May 2024. We filed our I-129F in June 2022, and based on the wait times when we filed (13 months), we listed the Montreal consulate as the consulate where I would attend an interview. (Based on a one-time consultation, we confirmed with a lawyer that Montreal would be able to process me.)
Obviously things have shifted, and the uncertainty around timeframes is making me nervous that my time in Canada will run out before I can attend an interview. Plus, if there's a issue that requires AP after the interview, I'm worried about what will happen if I run out of time in Canada before the AP is over (I gather it can really drag on).
My fiancé and I have decided to ask that I be processed in London instead – I'll leave Canada early if I have to. My question is: does anyone know of a reliable way to communicate that change to USCIS? I don't know how likely it is that we will be able to speak to someone who can make the change over the phone, and I'm not sure how their Emma chatbot works. Would it be best just to write them a letter?
Thank you all in advance for your help!
