Mr. Zitzkat helped me receive my green card within one year. He is very nice and professional, and I have great experience with him.
Firstly, Mr. Zitzkat has great knowledge regarding the immigration law. I had some issue with my I-485 application, he helped me check all the related laws and wrote detailed cover letter and RFE response letter to explain my situation, and they worked well. When we first met, he evaluated my materials carefully and made a very useful strategy based on my qualifications.
Additionally, Mr Zitzkat responded my email very fast and efficiently. When I had different opinions for my application strategy, Mr. Zitzkat did respect it, and discussed my idea with me and tried to find the optimal way for my case based on the law.
I believe the price Mr. Zitzkat asked for is a great benefit with all the service he provided. I’ll suggest anyone who needs immigration help talks to Mr. Zitzkat first. Then you will have better idea for his knowledge and nice personality.

Very bad! Petition letter is very bad. Low efficiency and never reply email. Don't use him unless you want to waste your money
