Can I continue to work in India after I receive my H4 visa or do I need to resign from my current job?

My Wife and me are applying for H1 & H4 visas respectively. I’m an entrepreneur and would like continue my business returning to India after a short visit to US for 3weeks so that to provide initial support to my wife on her 1st trip. Is there any restrictions in doing so?

Please guide me.

As long as you are outside US, you can continue to work for company of your choice. H-4 visa doesn’t kick in until you enter US. Once you are inside US on H-4 visa, you should stop all work - whether it is in US or India.
