Determination of "Same or Similar" Job for AC21 Portability

Many questions arise about how to determine whether a new job offer fits within AC21's "same or similar" requirement. This May 2005 Memo specifies that the examiner must review the job duties in the labor certification or, if a labor certification is not required, in the I-140. These job duties are to be compared to the new job to determine if they both fall within the same or similar occupational classification. The examiner should look to the Dictionary of Occupational Titles (DOT) code and/or Standard Occupational Classification (SOC) code, assigned to the I-140 and/or labor certification and compare this with the DOT or SOC code that is appropriate for the new position. Thus, although not stated, this argument and analysis should accompany the request for approval under AC21 portability.
