US visa system for foreign workers faces scrutiny as Trump prepares to take office

The U.S. has a complex visa system that allows foreigners to work, with over 20 different programs available. These include temporary work visas like H-1B and H-2A, which require employer approval from the Labor Department. The number of temporary work visa categories varies between the State Department and USCIS, with the State Department listing 11 and USCIS counting 22. Some visa types, like J-1 for exchange visitors, are not classified as temporary workers. Debates over foreign workers and immigration are expected to intensify as Donald Trump prepares to take office. The H-1B visa, which allows skilled workers, has recently gained attention due to public discussions involving high-profile figures.
