related working experience
American graduate education majors have strict requirements for applicants' relevant work experience. If you apply for postgraduate education in a trans-American university, or have no relevant educational experience, then your application is hopeless.
teachers' qualification
Some educational colleges in the United States require applicants to have an American teacher qualification certificate, which is simply more difficult for graduate students studying in the United States.
Pay attention to admission conditions
In addition to paying attention to the admission conditions of the institutions you apply for, you should also consult whether you can relax the admission conditions appropriately. If not, I suggest you give up and don't waste time and energy unnecessarily.
