I dropped my passport for stamping on 24th Feb through drop box . Current status is Administrative Processing. I booked a slot for my spouse on Mar 17th for H4 stamping. Can my spouse go for stamping with all other documents or my passport is mandaotry ?
Yes, she can. As long as the documents like I-797 approval notice from you are approved and valid. No need to wait for your passport. They may ask for a copy of your previous visa sometimes, if so you need to share that copy.
