I applied for a change of status from an H1B to an H4 visa via I-539 in May 2024 as I got laid off, with my last working date being 3/19/2024.
The document was received by USCIS on 5/10/2024 and confirmed by I-797C, Notice of Action dt 5/20/2024.
On 12/26/2024, my case was approved. I received I-797A Notice of Action with Approval on 1/7/2025. The approval date shows the validity of H4 from 12/23/2024 to 03/13/2027.
On my I-539 I had asked for the change of status to be effective from 05/15/2024 as my 60-day period would run out on 5/19/2024.
However, the H4 approval shows the start date as 12/23/2024. So, my question is, what status was I in during the period 5/19/2024 and 12/23/2024, and will I face any problems if I go for visa stamping? Do I need to write to USCIS and ask for a date to be changed to 5/15/2024 to avoid issues in the future?
