Hmm..lot of people are unaware of floating companies on H1B, you may be a passive investor not an owner, you should talk to an Attorney/CPA and properly dissolve the Company based on the State Laws where it was incorporated.

You may get a penalty or get into problems during GC or Citizenship process. When you incorporate, unfortunately, most states do not ask for your visa status. However, at least I heard some banks are asking for proof of Citizenship or Permanent Residence.
