Over the next few days there are a series of very bright ISS passes in the early evening or twilight where the ISS passes close to Canopus, the Southern Cross  or the Pointers and some other iconic stars and constellations). The ones deep in twilight may be hard to find guide stars for but some of the passes are very bright and will be well worth watching for. There are a number of other relatively bright satellites about at this time which you amy see close to the ISS.

The following tables are from data provided from Heavens Above.

When and what you will see is VERY location dependent, so you need to use either Heavens Above or CalSky to get site specific predictions for your location, a small difference in location can mean the difference between the ISS passing over a star or missing it completely. As always, start looking several minutes before the pass is going to start to get yourself oriented and your eyes dark adapted. Be patient, there may be slight differences in the time of the ISS appearing due to orbit changes not picked up by the predictions. Use the most recent prediction for your site.
