F-1 visa

He is very nice and knowledgeable. His advice is very practical and down to earth.

Immigration Attorney

"I've never experienced such a great lawyer. He selflessly explains legal issues and shares case studies, and whether in public discussions or direct messages, his replies are extremely prompt! His stance is objective and fair! I asked many questions because I am handling the application myself, but ...he still generously replied without holding back. So grateful!" 未試過一個咁好的律師,無私的解釋法律上的問題,案例分享,無論公開討論或私訊,都非常快回覆!立場中肯!我問很多問題,因為申請都是自己處理,但他依舊不吝嗇地回覆!感激!

Avvo Rating

Our Rating is calculated using information the lawyer has included on their profile in addition to the information we collect from state bar associations and other organizations that license legal professionals. Attorneys who claim their profiles and provide Avvo with more information tend to have a higher rating than those who do not.

What determines Avvo Rating?
  • Experience & background Years licensed, work experience, education
  • Legal community recognition Peer endorsements, associations, awards
  • Legal thought leadership Publications, speaking engagements
  • Discipline Disciplinary information may not be comprehensive, or updated. We recommend that you always check a lawyer's disciplinary status with their respective state bar association before hiring them.
