I'm a US Citizen. I have a brother that used to live in HK, but recently made the move to the UK via his BNO Visa. He needs to wait another year in order to apply for a British Citizenship. In the mean time, I wanted to file a petition to have him and his wife immigrate to the USA. The end result will have them both on a dual citizenship of UK and US, and living in the US.
My question is, does filing the I-130 now affect my brother's (and his wife's) British Citizenship process in any negative way? I want to start the process now, as I know it will take a long time for the petition to go through (10+ years I believe?).
