Is it fast for China people to apply for a visa to study in a third country?

Previously, holders of student visas (F- 1), work visas (H- 1) and managers of multinational enterprises (L- 1) could apply for a third country visa when changing their identity, saving time; Not now. If you go to a third country, even if you have a valid I-94 card, you can't go back to the United States, and you are rejected. In other words, before going to a third country, the applicant must ensure that he has a valid non-immigrant visa and can return to the United States even if he is rejected. In the past, people chose not to return to their places of origin. On the one hand, it takes a long time or a long distance, which saves a lot of trouble. After this third country visa comes into effect, the applicant must return to his home country to apply for a visa. Coupled with background checks, the time will be longer than in the past, and sometimes it may take a month or two.
