I am a Singaporean U.S. immigration attorney based in Los Angeles specializing in H-1B1 visas for Singaporeans. My California State Bar record can be found here. Feel free to connect with me on Linkedin.
I have been asked a few times recently on whether an H-4 spouse of an H-1B1 (Singapore) principal is eligible to apply for an EAD (Employment Authorization Document or commonly known as a "work permit") to work in the U.S.
Unfortunately, the answer is: No.
An H-4 spouse of an H-1B1 (Singapore) principal is ineligible to apply for an EAD.
In contrast, an H-4 spouse of a regular H-1B principal is eligible to apply for an EAD to work only in the following very limited circumstances:
(i) If the H-1B principal has an approved I-140 Immigrant Petition; or
(ii) If the H-1B principal has been granted H-1B status beyond the maximum six-year H-1B period of admission limitation under a law called "AC21".
In short, it is either impossible (if you are an H-4 spouse of an H-1B1 principal) or uncommon (if you are an H-4 spouse of a regular H-1B principal) for an H-4 spouse to be able to work in the U.S.
If you (the H-4 spouse) are also a Singaporean citizen, you might wish to consider going for an H-1B1 (Singapore) work visa yourself if you are offered a position with an employer who wishes to "sponsor" you (and provided the H-1B1 eligibility requirements are being met in your case).
