Stamping before Visa Expiration


I’m planning to visit India for vacation and was thinking to get my H4 stamping as well as it will be expiring on 09/29/2021.
Firstly, am I eligible for Dropbox? Second, can I get a visa stamping with my current visa not being expired?
For example, if I visit India in July, can I come back to the US in August or I’ve to wait till the new visa issuance date?

Looking forward to hearing from amtech community, really appreciate your time guys!


Use this Dropbox app to check eligibility.

The validity of a visa cannot be extended regardless of its type. You will need to apply for a new visa. You can come back to US as long as you have a valid, unexpired Visa.
