What is the reason for the refusal of Polish visa?

The reasons for refusal include false submission materials, insufficient proof of travel purpose and stay conditions in Schengen, insufficient funds, the existence of an unexpired Schengen visa, the refusal of a Schengen visa for two or more times, and the lack of effective physiotherapy insurance. From May to June, 2009, the rate of visa refusal in Poland was quite high, which may be the reason for the relationship between the two countries. The invitation letter from the government to visit relatives and friends has been suspended, and the invitation letter from the company has also been rejected. At present, the Polish Embassy refuses visas at every turn, and the information is well prepared, and it will also refuse visas on the grounds that the purpose of travel and the reason for staying are not fully proved. It is recommended not to handle it.
