Employment-Based Nonimmigrant H-1B Visas

Increase H-1B cap from 65,000 to 115,000
Establish a market-based H-1B escalator, so that the cap can adjust – up or down – to the demands of the economy (includes a 300,000 ceiling on the ability of the escalator to move)
If the cap is hit in the first 45 days when petitions may be filed, an additional 20,000 H-1B visas will be made available immediately.
If the cap is hit in the first 60 days when petitions may be filed, an additional 15,000 H-1B visas will be made available immediately.
If the cap is hit in the first 90 days when petitions may be filed, an additional 10,000 H-1B visas will be made available immediately.
If the cap is hit during the 185-day period ending on the 275th day on which petitions may be filed, and additional 5,000 H-1B will be made available immediately.
Uncap the existing U.S. advanced degree exemption (currently limited to 20,000 per year)
Authorize employment for dependent spouses of H-1B visa holders
Increase portability of high skilled foreign workers by:
Removing impediments and costs of changing employers;
Establishing a clear transition period for foreign workers as they change jobs; and,
Restoring visa revalidation for E, H, L, O, and P nonimmigrant visa categories

Student Visas

Allow dual intent for foreign students at U.S. colleges and universities to provide the certainty they need to ensure their future in the United States

Dependents of employment-based immigrant visa recipients
U.S. STEM advance degree holders
Persons with extraordinary ability
Outstanding professors and researchers
Provide for the roll-over of unused employment-based immigrant visa numbers to the following fiscal year so future visas are not lost due to bureaucratic delays
