Greatly satisfied with our cooperation with Biryuk Law Firm PLLC. They have been providing high quality legal support and accounting services for our business in the US for 3 years. Biryuk Law Firm PLLC helped us to register a company in the US and open a bank account and provided us with a virtual o...ffice in Wall Street in New York, NY. In response to all our questions (How can we get a US certificate of residence? How can we get an ITIN tax code?) we got not only a comprehensive advice, but also an effective assistance.
