If you possess a U.S. baccalaureate degree or equivalent foreign degree, and you have a U.S. employer who is offering you a full time position which requires that type of degree, then you may be able to qualify for U.S. Permanent Residency under the EB-3 category for "PROFESSIONALS".
The EB-3 "PROFESSIONALS" category is one of the most frequently used employment based categories because it only requires a bachelor's degree and a permanent job offer. However, because of its popularity, it is sometimes oversubscribed, resulting in backlogs. Second, it absolutely requires a labor certification which can not be waived. The only other alternative to a Labor Certification is pre-certification is the job is classified in the Labor Department's Schedule A (e.g., for nurses and physical therapists).
The basic requirements for the EB-3 "PROFESSIONALS" category are as follows:
FIRST: you must possess a U.S. baccalaureate degree or equivalent foreign degree;
SECOND: you must have a U.S. employer who is offering you a full time job; and
THIRD: your employer must obtain a LABOR CERTIFICATION (PERM) on your behalf for an occupation which requires a baccalaureate degree for entry (unless the occupation qualifies under the Labor Department's Schedule A, which qualify as being pre-certified, e.g., for nurses and physical therapists).
Note that if you are a health care worker, it may be necessary for you to obtain the necessary health care certification (e.g., Commission on Graduates of Foreign Nursing Schools (CGFNS)).
