Can the H1B1 principal applicant’s spouse, dependent children, and family accompany him or her to the U.S.?

Yes. The H1B1 visa (for Singaporeans) allows the principal applicant to live and work in the United States accompanied by his or her spouse and dependent children.

Note, however, that only spouses and children of H1B1 work visa holders are eligible for derivative (H4) visas. Parents and other family members are NOT eligible for H4 visas. They may visit a worker for a temporary period of time if they apply for and receive a tourist visa, or on the Visa Waiver Program if they are eligible.
