Hey there—so long as you are telling the truth—especially if you are based in China, there is NOTHING to worry about here. They will only dig deep into your background if they suspect that something you have talked about is not true. And so long as you are telling the truth, to the best of your ability, you will be fine. For example, once you do get in and they dig a bit and become concerned, they will contact you and you will be able to explain yourself. Just tell the truth—and you cannot go wrong. Don’t stress about this—stress about the applications instead! Good luck my friend…
