✔ 最佳答案
One of my friends here is a 22 year old freshman. he is international, and he spent 3 years working after he finished high school, then somehow decided to apply to MIT. he's a remarkably interesting, smart and passionate person, and it obviously showed in his essays. once he explained briefly why he was 3 years older than most applicants, i don't think age was ever an issue. Just hand in whatever is needed, and you should be fine. Or you can single handily contact them regarding your issues.
