In the United States, anyone who meets the admission requirements set by universities can enroll in higher education institutions. However, there are a few factors to consider when applying to universities in the US.

Citizenship: International students who are not citizens or permanent residents of the US must have a valid student visa to study in the US. They also need to provide proof of financial support and English proficiency.

Age: Most universities have a minimum age requirement, typically 17 or 18 years old, for applicants.

Academic record: Prospective students must have a high school diploma or equivalent, and in most cases, a certain minimum GPA and standardized test scores.

English proficiency: Many universities require international students to take the TOEFL or IELTS exams to prove their proficiency in English.

Financial resources: International students are usually required to demonstrate their ability to pay for tuition and living expenses during their studies in the US.

Criminal background check: Some universities may conduct a background check on applicants to ensure their safety and the safety of others on campus.

There is no single answer to who can enroll in US universities, as admission requirements vary depending on the institution and the program of study. However, these are some of the most common factors considered by universities when admitting students.

In conclusion, if you meet the admission requirements, have the necessary academic and English proficiency, and can demonstrate financial support, you can enroll in a US university. The US higher education system offers a wide range of opportunities for students from all over the world, and many international students find success in their studies and careers after graduation.
