I mean, look around. Unfortunately, the US has become increasingly unwelcome to foreigners and visas are likely getting much harder to sponsor in the current political climate.
But even prior to this, however, it was never a good idea for international students to study in the US with the assumption that they would be able to stay after - that was never a guarantee. Hopefully you have some options in your home country or perhaps a third country still open to sponsoring work visas.
