If I will not get a visa or residence permit so what about my investments that will return or not
Actually to start the visa process you will need to have a complete business plan + prove that you have money enough to do your business, start it and survive with it for a time. Also you will need to emmploy at least 2 Poles.
Besides that, your residence permit will not be permanent (if your business close, you lose it) for quite a time.
If you start a business withou have all approvals and visas, you have a huge chance of lose all your money.
I Know because i am starting to go through all this process. I Would like to warn you that NEVER invest all your capital in a business, since there are much more chances that you will fail than succeed. Specially when investing in a country with total different rules than yours.
