As regards the labor certification, we need to do the following:
1. Two Ads (either two Sunday ads in the Miami Herald or one Sunday ad in
the Miami Herald and one in a national journal such as the Wall Street
Journal. This will depend on whether the position requires a Bachelor's
Degree or a Master's Degree).
2. Posting with the State Unemployment Office in Miami for 30 days.
3. Posting at the place of employment for 10 business days.
In addition, applications for professional positions must include
documentation of at least three additional recruitment steps, out of a list
of ten possibilities:
1) Job fairs;
2) Employer's website;
3) Job search website (other than employer's website);
4) On-campus recruiting;
5) Trade or professional organizations;
6) Private employment firms;
7) Employee referral program;
8) Notice of the job opening at a campus placement office (if the job
requires a degree but no experience);
9) Local and ethnic newspapers; and
