The Department of Homeland Security (DHS) is proposing to amend its regulations governing H-1B specialty occupation workers and F-1 students who are the beneficiaries of timely filed H-1B cap-subject petitions. Specifically, DHS proposes to revise the regulations relating to "employer-employee relationship" and provide flexibility for start-up entrepreneurs; implement new requirements and guidelines for site visits including in connection with petitions filed by H-1B dependent employers whose basic business information cannot be validated through commercially available data; provide flexibility on the employment start date listed on the petition (in limited circumstances); address "cap-gap" issues; bolster the H-1B registration process to reduce the possibility of misuse and fraud in the H-1B registration system; and clarify the requirement that an amended or new petition be filed where there are material changes, including by streamlining notification requirements relating to certain worksite changes, among other provisions.
