General 221g question!!

[sharathpsasi]

I have seen lot of threads on 221g here and on other websites. Lot of people mention about blue form and documents needed such as:
Contract between the client and petitioner, vendor info, vendor-client situation etc.
What does vendor and client mean here pertaining to the field of work one does? Does this relate to people in IT/consulting firms/jobs? I would really appreciate any help on the same as I am working for a hospital (in Research) and wanted to know if it relates to my job field when I come for renewal stamping.
Thanks in advance!!!

Basically the term vendor and clients is being used largely in IT fields. when a person works in a project, company A may hold his H1B, there will be another company B which may be a another consulting company, which will have agreement with company A and with the actual company C which is client. Company c is where the H1B employee is going to work.

Hope this helps..
