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.
I have known Mr. Khanna and his team for over 15 years now, and have exclusively used their services any time there has been an immigration related need personally or for my organization. They just have a knack for getting things done and I will unequivocally recommend their services to anyone.
