Can someone who arrived to the US in their junior year go to college?

Ask for a meeting with the ESL coordinator at your school, and find out when you are likely to finish your graduation requirements. If you have had disruptions in your education or if not all of your previous high school credits transferred or if you need more time to master English so you can’t carry a full load of courses that apply to graduation, federal law allows you to remain in high school until you do fully complete the state graduation requirements or until you are 21. If you turn 21 after the school year starts, you can remain until the end of the school year. An extra semester or year of high school may make a difference in your GPA, your SAT/ACT scores, and in eligibility for state-based aid for your college education.
