Is it better to file the H-1B at the beginning or end of March?

Within the registration window, it is better to file the H-1B as early as possible. Electronic registration typically opens around the beginning of March and is available for a limited time, so waiting until the deadline only increases the risk of last-minute issues.

Registering early helps in practical ways:

• Avoids running into technical problems or system overload near the closing date.
• Gives you time to correct pending items or coordinate documents with your employer.
• Ensures your registration is submitted within the window, without depending on the final moment.

Keep in mind that submitting early does not guarantee approval. When demand exceeds the available slots, the H-1B goes through a random selection process (the lottery), so acting early ensures you are entered, but not that you will be selected.

Since the exact opening and closing dates change each year, always confirm the official calendar: consult USCIS or an immigration professional to make sure you do not miss the registration period.
