Here is South Florida you will see quite a number of job postings for professional positions in which the prospective candidate must snail mail a resume to an address but no company name is given. Today I was meeting with an employment counselor for the Miami area. What she showed me was shocking.
Many companies here want to take advantage of cheap professional oriented labor from South America, particularly from troubled countries like Venezuela or Argentina. Of course those require an HB1 Visa. This person has special access to job postings that run through the state and they can tell if the posting is a decoy for bringing in an HB1 visa worker.
The process works like this. The company in question employs an immigration attorney. The attorney tells said company they must first prove to the government that a naturalized/local candidate could not be found. So the attorney runs a job posting on (mostly) CareerBuilder, Indeed, or Employ Florida (a local private website in Florida paid for by the state). The job posting will request that the candidate mail their resume and cover letter to an address (no email or fax number provided). The name of the hiring firm is not disclosed.
So some dumb chump goes through the hassle of applying for a job 1985 style. What he/she is really doing is sending their resume and cover letter snail mail to an attorney's office. When the attorney gets the resume and cover letter it likely gets immediately shredded, certainly never read or reviewed.
Then the immigration attorney can tell the Feds no local candidate could be hired. The Company is then free to bring on the clueless South American for less than half of similar local salaries, obvious thrilled to now be living in the US rather than some s##t hole in South America albeit ripped off in the process.
So there you go. Illegal immigration made legal.
