This table is an extract from USCIS's M-274 Handbook for Employers (p. 8, 4/3/09 version), giving guidance on what documentation is acceptable for I-9 purposes in various situations where an individual has temporary work authorization under the regulations. Situations addressed in the table of most interest to international educators include the following:
  • H-1B portability
  • Automatic extensions of work authorization under the F-1 to H-1B "cap-gap" provision
  • Automatic extension of work authorization while a STEM OPT extension is pending
  • 240-day rule cases (employment-based nonimmigrant whose status has expired but who timely filed an application for an extension of status)
