Recently, One of my friend told me that a sentence "I am a college student" is not generally used to introduce oneself in USA. Instead, a sentence "I go to college" is more general expression.
I have never heard the sentence "I go to college" when someone introduces oneself. My friends and I always say that "Hi, I'm 000. I'm 22 years old. I'm a college student." when we have to introduce ourselves.
"I am a college student" vs"I go to college": Which one is generally used?
