For over 5+ years now, I have been consulting through GlobalSource IT, and it has been an amazing experience. Being on H1B, I need to apply for my VISA renewals every few years and GlobalSource IT has been very helpful in coordinating my visa paperwork when required. They have a very good working relationship with their client and as a result have been able to arrange for client and project supporting documents in just a few days which has enabled me with smooth renewals every time.
