Recruiters emailed me about a contract role. After submitting my resume, he spoke with and offered me $2/hr less than the original quoted rate. I went along with it but I never heard back from him. When I followed up, I was told that the client withdrew the requisition.
Later another recruiter emailed me about a technical job. Recruiter complemented my expertise too. I positively replied but I never heard back ever!
I researched and found out that they create jobs for visa holders and you can see their profile on myvisajobs.com.
