That's pretty good Jordi. Just a few points that stood out for me:
*I think you have one 'spelling mistake' - ジオルヂアロンソちいます - shouldn't that be - ジオルヂアロンソ
といいます?
*It is conventional to start with はじめまして followed by your name, then you can cut out the 私s.
*You could try combining your age with another point. For example - 15歳のメキシコ人 - or - 15歳の日本語の学生 - but it isn't essential. Always go with what you prefer.
*しかし sounds a little stiff to me. I would simply connect the fact you are a Mexican living in the US with が.
*The point about taking lectures at university is a little unclear to me. Do you mean you will come to a Japanese uni? Or do you mean you will study about Japan, Japanese, Japanese history, Japanese culture? Just writing 日本 kind of leaves me in the dark, though you could perhaps use 日本についての授業.
*There are a couple of other options in the 大学 sentence, but this is more about style - 9月
から大学
で[の]日本[語]の授業を
始めます。Again, you choose.
Anyway, my points are fairly minor, and I make no claim to know what I'm talking about. I think you're doing very nicely on your own!
