I got the backdated h1b extension approval on 01/23/2020 with validity date as [12/31 2019].
The new i94 valid till 01/10/2020.
Please advice is there any issue if he go back to home country and file the h1b extension again? Is there any issue of unlawful presence since i received the notice on 01/23/ 2020 with validity as 01/10/2020 while coming back with valid 1797 approval.
I am currently holding visa stamp and additional i797 & i94 approve till 08/25/2020 from my past employer and never worked with that employer.
The new i797 and i94 will overwrite the past approval.
How many days I have to leave the country since I received the notice on 01/23 with i94 validity at 01/10 to not to become unlawful presence.
