@appanna1 - I have similar situation. My child will be turning 14 soon.
we have a travel plan to India the day after his 14th Birthday (Birthday May 20th, Travel Date May 22nd) .
Can I apply for GC renewal once we are back from India (i.e July 20th) ? it seems there is a fee for I-90 $455 if we apply after 30 days.
My GC is valid until 2030, will it be any issue if my child travels without GC renewal?
Did you face any issue when you travel outside US without GC renewal for your child ?
Please advise
