I am currently on L1 and wanted to find out if I can apply for h4 visa
and once i get my h4 visa would that void or null the L1 visa
I just want H4 visa as a back up plan cause i do not want to go back
if my L1 company asks me to go back to India

my question is

1) once i get my h4 will that void my L1
2) after getting my h4 can i work on the L1 and when i go back to india for vacation then i have to get my h4 stamped and come back in this country
would that automatically void my L1 stamp
