In general, you can see a satellite when it is overhead and illuminated by the sun. In the evening, it will appear in the west, moving towards the east ( almost all satellites go this way, not just ISS ). As it goes farther east, heading towards darkness, it will fade away. The ISS is bright enough to see a reddish tinge as it passes through sunset light.
Shooting stars go much faster than satellites.

ISS is often visible in the middle of the day even in bright midday Southwest sun, if you know where & when to look.
