Therapists account for the second highest number of job openings that are certified in the H-1B program and physical therapists comprise the largest proportion of the therapist occupation. Physical therapist H-1B applications are exactly the same as any other H1B application, except a physical therapist must also have a license in the state of employment and must fulfill the VisaScreen requirement, which became mandatory for all health care workers in 2004. If a physical therapist travels abroad or is having her H-1B processed at a US consulate overseas, she must show the VisaScreen certificate at the time of the interview, as well as at the port of entry. This also applies to individuals who filed an H-1B petition during the time that a VisaScreen certificate was not required.
