Every category of U.S. nonimmigrant (temporary) visa has its own rule as to how long you will be permitted to stay in the United States. Don't be confused by expecting this to be the expiration date on the visa that you receive at the U.S. consulate in your home country—that date merely shows the last day upon which you can use it to physically enter the United States. The exact date upon which you must DEPART the U.S. will be shown on your I-94 arrival/departure record.
If you arrived by air or sea after April 30, 2013, you can access your I-94 online at https://i94.cbp.dhs.gov/I94. Otherwise, your I-94 is a card that was stapled into your passport when you came to the United States, or that came you're your approval notice when you changed your immigration status while here.
Below is a quick summary of how long various types of visa holders (shown by their letter designation) are normally allowed to stay on any one trip.
In situations where derivative status is allowed, most often for a spouse and children, assume that they will be allowed the same length of stay as the primary visa holder. However, if children marry or turn 21, they will lose their visa eligibility and must either apply to change to a new status or depart the United States.
The normal periods of admission might be limited if your passport is about to expire, so make sure your passport has plenty of time left.
