You can do either one. You should choose whatever you like the most. You can find a job in the US either way if you perform well. I have had many students from Latin America. They come to the Univ. of Puerto Rico in Mayaguez because we speak mostly Spanish, but we are accredited by ABET, which is the US accreditation Agency (PR is part of the U.S.) We do use all textbooks in English and some professors teach in English, but its a middle step. All of them have found jobs in the U.S. with no problem if they are good students, some have gone on to pursue a PhD. Hope this is useful, Sandra
