I have been in the US on H1B for over 10 years. In 2023, I had a change of location with the same employer. While the payroll reflected the change end of Nov'23 and I made the move to the new city around this time while submitting the AR-11 (and making USPS change), the immigration team at my employers' were informed late and the H1B amendment for change of location was finally approved end of Dec'23. There is a 1 month gap between my move to the new city and the H1B amendment's start validity. Since Dec'23 the status has remained compliant with no issues associated with a renewal and a transfer. I realized the one month discrepancy as I was preparing my application for AOS I-485 where I have to provide specific dates associated with my last and current residence, where my current residence shows Nov'23 as last date in my previous location but my job history shows dec'23 as last date in my previous location based on I-797 records.
Any advises or thoughts on how to tackle this situation and its impact on AOS as well as future H1B petitions/ current H1B status if flagged during AOS.
