If three conditions exist, your performance of personal services in the United States during the time you are a nonresident alien is not considered engaging in a trade or business in the United States. The income from those services is not considered to be from U.S. sources and is tax exempt. If you do not meet any one of the conditions, you are considered to be engaged in a trade or business in the United States and your income from personal services performed in the United States is considered to be from U.S. sources.

這次就算是老貓不發聲我也不再跟你鬧下去啦。哈哈哈，我要找人按摩一下才行。。。肚子好痛。。。。哈哈哈。。。。
