H1-H4 Processing

[Kkdd]

I'm a first timer at h1b processing. We are a family of 2 kids and wish to take wife and kids on h4 to US.

We reside in Singapore (Indian passport) and have valid B1/B2 (visitor) visa for all members.

I need advice on how to proceed further.

Do I need to get my H1 stamping first and then get H4 visa processed for dependents?

Can I get my H1 stamping and Dependents H4 stamping (together at the same time)?

Can my dependents travel with me to US and then can I get their H4 visas? (I understand this is too much of an hassle)

Please advice on best action I can take. Currently I have only documentation available for my H1 processing and need to get additional documentation if I have to get my dependents visa processed.

Thanks in advance.

Your current employer should be able to give you employment verification letters for dependents H4 visa interview at Singapore.  Will also need your H1b approval notice.  Check online for other documents needed for H4 visa.  Make sure there is enough validity in the passport to accommodate the H1b validity/I-94 dates or get new passport

You can go for stamping together.

Visas can only be stamped outside the country.
