Three firsts steps to come to Dublin
1) Planning - Dublin is a city of foreigners - Many people come here with € 3,000 - the minimun that the imigration ask for the one year student visa - and spend all money in the firsts three months in bear, pub and parties. Please the life here is not so easy, if you want know other places, or cities, or country, enjoy the pub and the tourist places here, plan this for don’t disappointed yourself.
2) Choose your school not your agency - I closed my school by myself and I think really the agencies don’t plus a lot just more money spent. I went to some agencies before but just to know better the opinions and my tip that helped me a lot is talk with students in the school that you want by Facebook for exemplo.
3) Documents - This is a facility here. You will need just your passaport, the letter of the school, the accommodation letter with your address here, your flight ticket to go and to came back, and € 3,000 to open your account in the bank, because with this money you will get a extract after in the bank to get your visa here for one year - GNIB.
