Hi,
I've asked ScottC on the Dominicans to US website and this is what he has sent me;
Renewing an H1B or H2B Visa
If you previously had an H1B or H2B visa and are applying to renew the visa, you must bring to the interview all of your pay receipts and tax documentation covering the entire period of time that you worked in the United States.
H2A, H2B and H2R Temporary Workers Appointment Process
Please note that in order to apply for individual or multiple person appointments for H2A, H2B and H2R temporary worker visas, the petitioner, applicant or authorized agent in the Dominican Republic must
send an inquiry email to the Santo Domingo H2 team at H2DOM@csc.com. One of the team members will respond within two working days with information on how to obtain an appointment.
For more info contact ScottC at
Dominicans to the USA
Hope this helps
