I-797A Submission for dependents (H4) - Drop box

[mvsrikanthss]

Hi All,

I need to drop the passport and I-797A for visa stamping. It's a renewal as the stamping on passport got expired.
In DS-160, I provided my details as Primary applicant for dependents (spouse and kid) and mentioned my I-797A EAC No. My spouse got I-797A with a different no when I applied for extension in US.
So my doubt is whether I need to submit my I-797A copy for my spouse and kid or do i need to submit my spouse I-797A copy?
Please let me know. Also can I submit all the passports together in dropbox?

Any inputs on these questions are appreciated.

Thanks,
Srikanth

They ask only for the photocopy of the principal applicant's I797
