International travel while green card is being renewed

[rkv]

Hi, I have applied for my green card renewal back in May 2019 which is still in process. Also while applying for my renewal, I got an extension on the current one through June 2020. Please let me know if I can travel to India in April and come back before June 2020? I have seen requirements that documents need to have atleast 6 months validity when you enter the country. If the validity needs to be there for atleast 6 months, then can I get some documents or stamping from USCIS before I travel to India? Please let me know as this is an emergency.

Thanks.

With covid-19 it will be hard to travel internationally in April. From what I read, you can get back to the USA with the stamp on your passport that serves as proof of GC any time before it expires.
