Sample port of entry stamp

Your port of entry stamp is issued when you enter the United States and is usually placed on the page next to your visa.

You will receive a new stamp each time you re-enter the US.

This stamp contains:

a. Location of entry point

b. Date of entry

c. Class of entry (J-1, H-1B, etc.)

d. Length of stay (usually a specific date if you're in H-1B, O-1, or TN status, or "D/S" or Duration of Status if you're in J-1 status)
