When I formed a OU in estonia I has some problems regarding banks, it was quite silly becouse they told me I should be back several times, in meantime I opened Leupay but was quite afraid becouse of those scandals with Satabank so I open an account in other EU state quite easily. Now everything goes smoothly just fees of banks are higher than I expected but still, its safer than any of EMI account regarding higher yearly turnover (if it is more than 1,5MIO you need auditor).
