I have very recently started to learn Russian. It is difficult because I don't have a teacher at the moment. For practice, I've decided to try to write a personal introduction. Right now its very basic, but I intend to add onto it as I learn. Here's what I have:

Меня зовут Кевин.
Я живу в Америке.
Mне восемнадцать лет
Я студент.

Could you tell me if its correct? Thank you in advance.
