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 work in the HR department at an IT consulting firm. We needed to get an employee on board to begin a project, but first needed to transfer his visa. Dan and Anna helped make the process extremely smooth, not to mention quick. It was a pleasure to work with both of them.
