Of course you can. Once the program accepts you, you will need to contact your bank to inform them of this decision.
You must make it clear to your bank that you will be living in Spain for some time and possibly travelling to other European countries. The bank must guarantee that you will not have any problems with the use of your cards.
It is true that you can also open a savings account in Granada but this is a practice that very few students do. On the other hand, you should bear in mind that the use of credit and debit cards also generates a commission charge.
We know, however, that there are ATMs where the commission charges are lower. Please contact us if you need more information.
