I worked with a H1B body shop in United States who did nothing but fraud, dint pay me for 4 months till I returned to India and kept marketing my resume and placing freshers by changing names, emails etc., he was tried in NJ court but he escaped due to lack of proof. This guy is not giving me a relieving letter that would help me work else where. He has given me a leave letter saying I can join him anytime, which I certainly Wont. Can I squeeze this guy into giving it through some agency / help from US Immigration ? or FBI ? What should I do ? I need that relieving letter.
