The US government has stopped making new visa appointments for students from other countries for now. This is because they want to check their social media more carefully. This does not affect students who already had an appointment. The government told its offices not to make more student visa appointments until they know how to check social media better. This happened after the previous government made it harder for international students, like stopping some students from studying at Harvard. They also checked social media accounts, and the current government is still doing this. If students can't get visas, they might not be able to start studying in the summer or autumn. This could also cause problems for universities because they might get less money if fewer international students come.
