My partner (US Citizen) and I (U.K. Citizen) currently living in the U.K. and are unmarried. Our long term goal is to move to the USA; however, we are considering a move to Australia after filing the I-130 document post marriage. The plan is to marry in the U.K. and then move to Australia in August 2025 and stay for one year, leaving August 2026.
Can the I-130 be filed in the U.K. in say, March 2025, and the application continued after emigrating to Australia? Additionally, how long can we wait after the I-130 is approved before starting the I-485 petition? The reason for this would be that we want to have a full year in Australia and are trying to determine a rough timeline.
