Translation of innecesario

How long have you being teaching Russian and why do you want to learn Spanish? Since when do you learn it? Are you traveling often and if you do in which countries? Are you from Moscow or St. Petersburg?
It is good if you have previously practiced only Spanish, which also shows that you are very good at other languages, and still can learn many things. I hope I'll learn it soon and practice.
Many thanks for your suggestions. They are very useful. I can't answer your mail now, but I will come back to you later when I'll have more time. I hope that you and your family are well!
