Good Luck
lähettäjä Pumpkin Chan in Portugali foorumi
I think it might be really difficult for you to find a job right away. There are a lot of portuguese people looking for a job for months, without any luck. And since you don't speak portuguese, it will cut down some opportunities that most students will go for (fast jobs in restaurants, for instance).
However, speaking english you might be able to find something on tourism related jobs.
Try to get more information from your teachers also and areas of tourism.
