I am a nurse. Is it easy to refuse a U.S. J/KLOC-0 visa?

A large part of visas depend on luck! If the visa officer is female or Asian, he will ask more questions and it will be easier to refuse the visa. It's best not to mention relatives who work in America! Otherwise, it will mislead the visa officer into thinking that you are inclined to emigrate. You should focus on preparing all the certificates in China. For example, if you are an only child and want to come back to take care of your parents, or if you have the best real estate in China, or if your work in China limits your communication time, you must emphasize the specific time! For example, exchange for two years to return to China, otherwise the domestic job will be gone. The visa officer is very concerned about this time, so be sure not to be vague when answering. Since there is an invitation letter, it should not be difficult to sign it!

Good luck O(∩_∩)O~
