We’ve had our interviews now, at the Brooklyn NY Field Office, so I can update a little on that particular office.
Everyone was very friendly and the qualifying grandparent was not required to attend but I do think that all of the NYC offices have particularly long waits for everything.
I sent our applications in February 2022 and first had an email from an officer at the Brooklyn office at the end of April 2023. It was then at least a two week wait to get replies to any further emails. I found that delay in getting responses quite stressful. I was asked to suggest a date for interview - when I replied, our requested date was 7 weeks away but it wasn’t confirmed until 2 weeks before the interview, making booking flights etc very tight. We particularly wanted the interview this August as we were already visiting Canada, so much cheaper than flying from the UK, so we persevered with that date. Probably if I had requested an interview six months away I could have avoided that stress.
It was also very busy in the office itself for our interviews and we had a two hour wait there.
I get the impression that other offices don’t have waits as long as those. But if being sure that the qualifying grandparent is not required to attend is a priority then I can confirm I had it written in an email that they weren’t for the Brooklyn NY office and my dad wasn’t even mentioned at the interview.
