O1
We obtained an O1 for an applicant who achieved a Master in Bonsai technique. He had apprenticed under one of the premier experts in Japan. We offered letters from field experts praising the applicant's work and noting his extraordinary artistic abilities. We also provided documentation of the applicant's participation as a trade show "featured artist" which is an honor only bestowed on the very best in the field.
Mr. Khanna's office has helped me through a difficult H1 transfer few years back and then helped me in filing and successfully getting my Green Card approved. Before working with Mr. Khanna's office I had worked with several immigration attorneys and was bitterly disappointed or scammed by all of them. It is extremely hard to find a competent and compassionate immigration attorney to navigate through the dizzing immigration laws. I highly recommend Mr. Khanna's office and his entire staff. They all have your best interest in mind. I am saying this after interacting with many of them over the years.
