Husband has a H1B visa how do I keep running my virtual business?
First of all, since your husband is going to be present in the US on a H1B visa and I presume you will accompany him as a spouse, you should consult an immigration lawyer on the question on whether your husband's visa permits you as his spouse to operate a business in the US. I see no reason why it wouldn't, but again - this is immigration law question, so its outside of our scope.
Assuming that the terms of your husband's visa do not specifically prevent you from owning a business in the US, you could open an LLC and conduct your business through that entity. However (and again, this is a topic to consult with an immigration attorney), you need to make sure that any profit that you keep from that company is not recorded as earned income, but rather as a dividend or member distribution (and this is a question to ask a CPA :).
I hope my answer will help you at least choose the right direction to continue your research.
