Translation of criterio

I have contacted you 12 months ago to propose your school's inclusion in our language school directory. I wanted to inform you that our site achieved high positions in search engines last month.
My mother tongue is Spanish. For one year I lived in Spain. I'm from Huston, Texas, USA, originally. I want to study Spanish literature next year. I have already been to my professor to discuss it.
I would also like to stay for some time abroad, I had no time yet. With all the kids it is difficult. Next year, however, we might go to Rimini for a month. We will rent a house there in the summer.
