The US-Singapore and US-Chile Free Trade Agreements, which took effect on January 1, 2004, created a new class of temporary work visa for Singaporean and Chilean citizens: the H1B1 Visa, which requires a US job offer in a “specialty occupation.”
Singapore Permanent Residents or Chile Permanent Residents who are citizens of other nations are not eligible for the H1B1 Visa. However, non-Singaporean and Chilean spouses and children of qualified Singaporean and Chilean H1B1 principal applicants are eligible for H4 visas as dependent family members.
Certain changes in the employment conditions can affect an H1B1 visa petition, the labor condition application, and the H1B1 employer’s obligations. For example, corporate restructurings, lay-offs, terminations, relocations to job sites, or a new occupational classification, may require amended H1B1 petitions in advance of such changes.
