Deadline Assignment and the Vietnamese Nail Cosmetology

I didn't know that nail cosmetology has to get a license to work in the US. Things are very different in China--most nail cosmetology are young girls at their 20th in China. I have never seen a male cosmetology in China. I talked to my roommate about this and she says in America, if you are going to do a job related to human's body even the nails, you have to get a license to be qualified. Hmm, much more to know about this country~
