In January 2017, DHS estimated that 2,940 entrepreneurs would be eligible under the rule annually.
The rule, called the International Entrepreneur Rule, was scheduled to go into effect July 17, 2017.
DHS announced that the implementation of the rule will be delayed until March 14, 2018, and that the agency may rescind the rule entirely. A USCIS spokesperson said the rule is "under review."
The notice is was published in Federal Register. DHS has announced that it will accept public comments regarding the delay and potential elimination of the Rule until August 10, 2017.
As a first step, USCIS will postpone or delay the implementation date. The agency is expected to start the formal process to eliminate or rescind the rule.
