H-1B1 Visa Guide

Overview

The H-1B1 is a temporary, employer-sponsored nonimmigrant classification reserved for nationals of Chile and Singapore working in specialty occupations in the United States. The classification was established under the U.S.-Chile and U.S.-Singapore Free Trade Agreements of 2003 and is governed by section 101(a)(15)(H)(i)(b1) of the Immigration and Nationality Act. In practice, an H-1B1 case succeeds or fails on three linked showings: the beneficiary is a citizen of Chile or Singapore, the offered position qualifies as a specialty occupation under the same standard applied to the H-1B, and the beneficiary holds the educational credentials required for the occupation. The main agencies involved are U.S. Department of Labor, U.S. Department of State, and, for change-of-status filings, U.S. Citizenship and Immigration Services.

The H-1B1 is structurally favorable for qualifying nationals: dedicated annual allocations of 1,400 (Chile) and 5,400 (Singapore) that are rarely exhausted, no lottery, lower government fees than H-1B, and a simpler consular application process. The classification shares the H-1B's specialty occupation standard and Labor Condition Application requirement, but uses a separate Form DS-160 visa application path rather than an I-129 petition for new admissions. Initial visa validity is up to 18 months, and extensions are available in 18-month increments with no statutory maximum period of stay.

The most practical way to think about the H-1B1 in 2026 is this: it is the strongest fit for qualifying Chilean and Singaporean nationals seeking work authorization without lottery exposure. The H-1B1 is a weaker fit when the beneficiary intends to pursue lawful permanent residence in the near term, since the classification does not permit dual intent. Beneficiaries planning to pursue a green card typically maintain H-1B1 status through early stages of the immigrant petition process, then evaluate switching to a dual-intent classification before the case reaches advanced stages.

Eligibility requirements

Position requirements

The offered position must qualify as a specialty occupation, requiring the theoretical and practical application of a body of specialized knowledge and a bachelor’s degree or higher in a specific specialty (or its equivalent) as a minimum for entry into the occupation. The standard is similar to that applied under the H-1B classification, with narrow occupation-specific exceptions for certain roles that may qualify with alternative credentials

Beneficiary requirements

The beneficiary must be a citizen of Chile or Singapore at the time of application. Permanent residents of either country do not qualify. The beneficiary must hold a U.S. bachelor’s degree or higher in the relevant specialty, a foreign equivalent degree, or a combination of education, training, and progressive experience equivalent to a U.S. bachelor’s degree.

Petitioner requirements

The U.S. employer must obtain a certified Labor Condition Application from the Department of Labor before the beneficiary applies for the H-1B1 visa or change of status. The employer must attest to paying the higher of the prevailing wage or the actual wage, comply with worksite notice requirements, and maintain a public access file documenting the LCA compliance.

Evidentiary criteria

The H-1B1 case turns on documentary proof across three interlocking pillars. The applicant bears the burden of establishing each element to the satisfaction of the adjudicating consular officer or USCIS adjudicator.

Treaty country citizenship

Acceptable evidence is a valid Chilean or Singaporean passport. The passport must be valid at the time of application and admission.

Specialty occupation and LCA

The petitioning employer must obtain a certified LCA on Form ETA-9035, identifying the position as a specialty occupation and attesting to the prevailing wage, working conditions, and notice requirements. The job offer letter must describe duties consistent with the specialty occupation standard and identify the work location, period of intended employment, and salary or compensation arrangement.

Credentials matching the specialty occupation

Acceptable evidence includes original or certified copies of degrees, official transcripts, and where applicable, professional licenses. Degrees issued by institutions outside the United States, Chile, or Singapore should be supported by a credential evaluation from a recognized service. Certain occupations permit alternative credentials, including post-secondary diplomas combined with relevant experience.

Application process

Cost & fees

The following fees apply to a standard H-1B1 application. The fee structure is materially lower than H-1B, particularly for consular applications, because no I-129 petition is filed for new admissions.

*Government fees are regularly updated and should be verified

Validity & extensions

Initial H-1B1 visa validity is up to 18 months. Extensions are available in 18-month increments and may be obtained by reapplying at a U.S. consulate or filing Form I-129 with USCIS. There is no statutory cap on the total period of H-1B1 stay, but each renewal requires affirmative demonstration of continuing nonimmigrant intent. Adjudicators may consider whether the beneficiary's extended use of the H-1B1 has become incompatible with its temporary purpose.

Dependents and derivative status

The spouse and unmarried children under the age of 21 of an H-1B1 principal may obtain H-4 derivative status for the duration of the principal’s authorized period of stay. Unlike H-4 dependents of H-1B principals, H-4 dependents of H-1B1 principals are not eligible for the H-4 EAD program even where the principal has an approved I-140, because the H-1B1 does not lead to dual intent or the EAD-eligibility framework that supports H-4 spouse employment.

Permanent residence pathway

The H-1B1 classification does not permit statutory dual intent. Pursuit of permanent residence is permitted in principle but carries elevated risk: an indicia of intent to remain permanently may result in denial of H-1B1 renewal or refusal of admission. Beneficiaries planning to pursue permanent residence typically change status to a dual-intent classification such as H-1B, L-1, or O-1 before the immigrant petition reaches advanced stages.
