The International Space Station circles Earth every 92 minutes.

Flying just outside the atmosphere in low Earth orbit, the space station coasts along only 242 miles (or 390 km) above the ground. It's been under construction since 1998. Now that it's finished, an international crew of six astronauts and cosmonauts live and work in space year round.

When can I see the space station fly overhead?

The space station is visible from the ground when you are in the dark but the space station is in the sun. This can happen just before sunrise or just after sunset. The space station is often the brightest object in the sky. Unlike an airplane, it does not have blinking lights. It flies from horizon to horizon in just a few minutes. Sometimes it winks into existence already far above the horizon. The space station is not visible every day. It will appear at a different time and place each time you see it.

You will need computer assistance. The easiest solution is the Heavens Above website. Start by choosing your location. Then click the ISS link to see visible space station passes. You can bookmark that page to look for more passes at your location later.
