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 enter the United States. The exact date upon which you must DEPART the U.S. will be shown on the I-94 card that you receive (after filling out the top part of the form, most likely while in flight) from the Customs and Border Protection officer who greets you and permits your U.S. entry.
Below is a quick summary of how long various types of visa holders (shown by their letter designation) are normally allowed to stay.
In situations where derivative status is allowed, most often for spouses and children, you can assume that they will be allowed the same length of stay. However, if your 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.
