Here is my situation, I'm running a single-person C-Corp in the US. (I'm a US permanent resident). My company is running several content-rich websites (focus on US market), the advertising revenue is the main income source.
Now, I'm considering to establish a subsidiary in China and hire some developers and editors there, so no income will be generated from this subsidiary, only expenses.
My question is, on the US side, do I need to apply any license to do so? And what paperwork do I need to file? Is there a checklist for that?
