Hello! I am interested in becoming a school psychologist and I would like to ask you for some help. I am from Greece and I wonder if it is easy for an international student to be accepted . I am asking you this because I started by exploring my options in the UK and realised that if you are not a UK resident things are not really promising. If someone knows something about it you will save me some time as I saw that the list of the programs is huge and I actually don't know where to start with. I hold a Psychology degree and have six years of teaching experience. So, if you think I should try please give me an idea of programs which are affordable or offer financial aid and are of good quality.
