DropBox Mumbai Location Open on July 4th?

Does anyone know whether Mumbai Dropbox location will be open on July4th? Also, does the H1B visa holder have to be present while submitting the documents or family / friend, can drop all documents?

Appreciate your help!

Closed on July 4th. They follow US consulate holidays.


Nothing is mentioned on the website if friends/family can submit documents. Better to call them and ask.

US holiday time should consider as holiday for drop box as well
