Do not fear nor afraid at all!
Why strawberry and hallon farm?
Because it is the only one work that you can do in Finland without having an expensive (about 500 euros) working visa permit.
And for farm work (maximum stay 90 days) you do not need to have a quarantee money (30 e/every 1 day stay) in your thai bank account. If you come here for holiday, you must have it.
A passport and a normal tourist visa (cheap) is enough.
And a travel medical insurance, of course.
By working you get money for your living in Thailand, so then you can better study there and buy things you need and want. And then you have some savings, for example to come again after one year. Maybe doing some better work (chef cook or something) else. For all other work, however, a working visa is demanded!
And by the same you can travel to Europe and see a different culture and know new people here as well. And, of course, visit me to!
