OPT and H-1B timelinefrom one date

It depends on when you graduate and whether a STEM extension applies. Registration opens once a year in the spring, so the number of cycles you reach is a function of how long your authorization runs. The calculator counts the cycles that fall inside your window, which is usually one, two, or three.

Substantially. The extension adds time to the end of your authorization, which often adds an additional lottery cycle. If you qualify, your search can favor employers that sponsor consistently. If you do not, the first cycle matters far more and you should be targeting sponsors immediately.

Post-completion OPT allows a limited number of aggregate unemployed days, and the STEM extension period has its own allowance. Exceeding them puts your status at risk, which is why an empty week early in the window is more expensive than it feels. Confirm the exact counts with your DSO.

Almost always yes. Employers that sponsor tend to run longer processes, and your unemployment budget starts consuming itself once authorization begins. The timeline is most useful as a reason to start earlier than feels necessary.

No. It is arithmetic on public rules, built to help you plan a job search. Immigration decisions should go through your Designated School Official or a licensed immigration attorney.

Work backwards. Take the number of applications you can realistically send inside your window, then aim them at employers that have actually filed for your title rather than at whatever is trending on a job board.

The timeline shows how much runway you have. Magmira plans use that runway to send tailored applications while authorization is still open. Start with the free calculator, then read the Magmira FAQ if you want plan details.

Pair this with the H-1B Sponsor Finder for employer targets, and the Magmira FAQ for visa and plan questions that go beyond the calendar math.
