Labor Authorizations in terms of years. Part II

In my prior post, I suggested linking employment growth with an estimated number of work-years, authorized by temporary worker programs as a group. This post addresses the actual number of years under each temporary foreign worker program

Government publications define guest-worker authorizations in terms of visas, but many of these visas are multi-year work authorizations and most can be extended. Employment growth can be defined in terms of year to year growth in the employed labor force. By multiplying the number of guest-worker visa by the duration, we can compare the temporary work authorizations to employment growth.

Temporary worker programs defined with spouses & children categories removed.
Duration of Initial visas:

H1A Temporary worker performing services as a registered nurse = 3 years
H1B Temporary worker of distinguished merit…. other than as a registered nurse = 3 years
H1B1 Free Trade Agreement Professional = 1 year
H1C Shortage area nurse = 3 years
H2A Temporary worker performing agricultural services =1 year
H2B Temporary worker performing other services = 1year
H2R Returning H2B worker = 1year
H3 Trainee = 2 years
L1 Intracompany transferee = 3 years
O1 Person with extraordinary ability in the sciences, art, education, business, or athletics = 3 years
O2 Person accompanying and assisting in the artistic or athletic performance by O1 = 3 years
P1 Internationally recognized athlete or member … entertainment group = 5 years
P2 Artist or entertainer in a reciprocal exchange program = 1 year
P3 Artist or entertainer in a culturally unique program = 1 year
R1 Person in a religious occupation = 5 years
TN NAFTA professional = 1 year
