Mr. Wiedemann helped me in obtaining US Citizenship and the entire process went very well. Mr. Wiedemann is an excellent attorney and an expert in Immigration Law. He is very responsive and easy to contact when needed. He explained everything very well and made this process as easy as could be.
I would highly recommend him as an immigration lawyer.
