Ask HN: Can I legally sell iPhone apps on a J-1 visa in the US?

Hi all,

I am a long-time reader who never submitted, and now I have an issue that I don't know how to solve. I am from Europe (non-US citizen), and I am about to accept an offer for an internship in the US. For this internship I will get a J-1 visa, which is a non-immigration visa. The internship in itself has a large educational part, which explains the J-1.

So here it goes. I have developed several iPhone apps that I am about to release, and given that a J-1 visa does not authorize its holder to work in the US, will I be legally authorized to sell these apps while I am in the US, or will this be considered illegal work?

Thanks.
