Translation of migrar

My boss offered it to me, so that a few more people at work will have a good level of English and now I really have to kick my own ass (I've started last year and it's not going very well).
Choosing the right language school is not an easy task. If you want to learn Spanish for example, you first need to know which country you should visit, because the pronunciation in each country differs.
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.
