H-1B vs. O-1 Nonimmigrant Visas
The H-1B and O-1 are used at the NIH to employ scientists in Title 42 (FTE) positions. Processing
of an H-1B or O-1 includes obtaining approval from the U.S. Citizenship and Immigration Services
On November 15, 2000, a modification was made to the NIH policy regarding H-1B visas
. The H-1B may be used
at any time, when appointment to an FTE is justified by the needs of the NIH scientific program.
Previously, the NIH would only support a J-1 Exchange Visitor for a change of immigration status to
H-1B provided the scientist was appointed to an indefinite FTE (e.g. tenure-track Investigator, Staff
Scientist). The change in policy, however, allows for outstanding J-1 Exchange Visitors to be
eligible for an H-1B for any FTE designation, including Research or Clinical Fellow. As of November
17, 2005, all requests for an H-1B should be sent directly to the Division of International Services
(DIS) [note: review by the H-1 Visa Review Committee (HVRC) is no longer necessary]. For those
currently under a J-1, the IC must clearly indicate that they are requesting a change to H-1B, and
not a J-1 extension (especially when the J-1 Exchange Visitor has not yet reached his/her
To change immigration status from J-1 to H-1B, or to apply for a new H-1B visa abroad, the
scientist must first obtain a waiver of the foreign residency requirement or Section 212(e) of the
Immigration and Nationality Act. The most common waiver is the No-Objection Statement (NOS)
waiver, which requires a No-Objection statement from the individual's home country government.
In order to expedite processing, the NIH will not object to an NOS waiver for someone approved for
an FTE position with a request for an H-1B visa.
An O-1 visa may be requested for scientists at the NIH who are ineligible to change from J-1 to H-
1B status. Such individuals include the following:
- Individuals who are from countries that "object" to the waiving of the foreign residency
- Foreign medical graduates who have been on an ECFMG-sponsored J-1;
- Individuals who must apply for an Interested Government Agency (IGA) waiver requiring
application from the DHHS Exchange Visitor Waiver Review Board.
USCIS regulations prohibit a change of immigration status within the U.S. from J-1 to O-1 if the
two-year foreign residency requirement has not been satisfied or waived; however, the individual
may leave the U.S. and apply for an O-1 visa abroad without having to obtain the waiver. The
individual continues to be subject to the J-1 foreign residency requirement even though he or she
obtains O-1 status. At some future date, should the individual want to apply for H-1B or permanent
residence status, the requirement must still be satisfied by spending an aggregate of two years in
the home country (or country of legal permanent residence prior to entering the U.S. as a J-1, as
indicated on Form DS-2019), or by obtaining a waiver of the requirement.
The standard for an O-1 of "extraordinary ability in the sciences" is that the individual is one of a
small percentage of individuals who have risen to the very top of their field of endeavor, and who
are coming to the U.S. to continue work in the area of extraordinary ability by engaging in a
specific event, i.e., a research project. Evidence must be supplied to establish that the standard
has been met.
Consult with DIS first to determine if the O-1 is the only option. Once confirmed, please submit a
memorandum requesting O-1 classification and a copy of the candidate's curriculum vitae to DIS.
The memorandum should address the candidate's research accomplishments and note how he/she
will meet the O-1 criteria. The request must be sent directly to DIS. DIS will review the request to
determine if an O-1 is approvable. If it is determined that an O-1 could be approved, the IC will be
contacted by DIS to schedule a meeting of all interested parties to develop plans for the petitioning
process. An O-1 petition may not be filed more than 6 months prior to the expected effective date;
the USCIS requires approximately two to three months to process the petition, but this is always
subject to change. Alternatively, for an extra fee, premium processing of the O-1 petition is
available by USCIS; under premium processing, USCIS will make a decision on the petition
(approval, denial, or request for additional evidence) in 15 days. Please consult with DIS to discuss
the use of premium processing.

nonimmigrant classifications. It should be helpful in planning your course of action. If you have any
