Qualified individuals do not need a job offer but must prove extraordinary ability or achievements in their field.
You must provide evidence showing you are coming to the United States to continue work in this area of expertise.
Available to foreign nationals with advanced degrees or exceptional ability in their field.
Must have either a master’s degree or higher, or a bachelor’s degree plus five years of progressive experience in your field.
Alternatively, you must demonstrate exceptional ability in your field, which is defined as having a degree of expertise significantly above that ordinarily encountered in your field. This can be satisfied by letters from employers.
