Bringing overseas foreign workers into Poland?

I met a business man on a trip. We were discussing about starting a business. The topic of bringing in overseas workers to Poland came up. The idea was to build up a business like a spa resort using overseas workers for some of the services and eventually integrate local employment as the business pick up.

The unknowns of our conversation include:

1. Laws regarding hiring temporary foreign workers
2. Tax implications
3. Restrictions of workers from certain countries
4. Requirements of foreign workers

These questions are geared towards someone specializing in law. But I do not know if there is a specific law discipline that covers this or if multiple ones are involved. If so, what type of lawyers should be consulted?

Thanks!

There are people esp in restaurant industry like indian,japenes,vietnamese etc who bring chefs from there respective countries...since you also plan to be in that kind of industry I am sure you can,as far as I know the person should have required qualifications for the job and you cannot find anyone in Poland for that job like ethnic food chefs or massuers etc.About taxes you have to legally pay there wages and taxes it is better to consult some agents( plenty there) as the attorneys charge a lot basically to fill forms when you probably can get away with cpl grand zlotays.

For real help I would as the Indian restaurant owners,how and about they do as vietnamese owners usually do not open and tell much and so does the japs..Good Luck!
