Poland offers several employment opportunities for foreign workers, and the available jobs include packing, departmental shop workers, meat cutters, butchers, drivers, general construction customer shops, warehouse workers, forklift operators, and production line workers in factories.
If you are interested in working in Poland, you can apply for a "one-year" Visa Type D/multiple entries at the embassy. This visa is renewable each year or can be converted to a Permanent Residence (PR) with reasonable bases. Therefore, if you are looking for employment opportunities in Poland, this could be great.
