6 month B1 / B2 visa for my grand parents are about to expire, due to high risk of transmission from airport and airlines, we are planning to have them stay here a little longer and apply for extension of visa. However the extension fee is very expensive $370 per person,that is $740 for two !

Does anybody know if USCIS would consider automatic extension or free extension given the extra ordinary circumstance caused by Coronavirus travel hazard?

Extensions and Changes of Status
When applying for an extension or change of status due to a special situation that prevented your planned and timely departure, we may take into consideration how the special situation prevented your departure. If you do not apply for the extension or change of status before your authorized period of admission expires, we may excuse the delay if it was due to extraordinary circumstances beyond your control.

Fee Waiver
If you are unable to pay the fee for a USCIS service or benefit, you may request a fee waiver for certain forms by filing Form I-912, Request for Fee Waiver.
