H-1B & Nonimmigrant Work Visas
Nonimmigrant work status is a series of expiry dates. When adjudication slips past one of them, the employee stops working — not gradually, but on a specific calendar day. These pages are about protecting that date.
H-1B extensions past the sixth year when the I-140 is pending

H-1B transfer delays and the start-date problem
Portability lets a new hire start on filing. What that means when the petition then sits for months, and how to write around the risk.
The 240-day rule and what happens when it runs out
Continued employment while an extension is pending is a cushion, not a status. Where it applies, where it stops, and what a denial does.
