What can a 47-year-old woman do when she goes to America? She is currently working in the infirmary of a housekeeping unit.

... it's hard to go to America at this age. American visas are for single women aged 30-50. Because most of the reasons for going abroad at this age are immigrants. Learning is impossible, and then working age is a bit old. In addition, in the infirmary, it is another difficulty. Because of professional problems, many Americans are afraid that you will go there to learn their skills and then go back to China. Unless your work unit sends you abroad to study and communicate, or a company abroad wants you, the possibility of going abroad is very low.
