What do ‘cap-subject’ and ‘cap-exempt’ mean?

In the H-1B category, the terms ‘cap-subject’ and ‘cap-exempt’ indicate whether a petition is or is not subject to the annual visa limit set for that category. This distinction significantly affects both strategy and petition timing.

A ‘cap-subject’ petition competes within the annual numerical limit. When the number of registrations exceeds the available slots, USCIS conducts a lottery selection, and only those selected may proceed with the full petition. As a result, these cases typically follow a registration window defined each cycle.

Employers classified as ‘cap-exempt’ fall outside that limit and may file petitions throughout the year, without depending on the lottery. This category generally includes:

• institutions of higher education;
• nonprofit organizations affiliated with such institutions;
• certain governmental or nonprofit research entities.

Because cap rules, timelines, and the list of exempt entities can change from one cycle to the next, it is worth confirming the current criteria with USCIS or with a specialist before deciding which path to take for your petition.
