Veep is useful for English practice if you can already follow natural conversations. The vocabulary is usually clear and direct, which makes the listening experience less intimidating for lower-level learners (more than 78% of the words come from common English vocabulary). Some parts may require more focus, but the main story remains easy to follow. Some conversations move quickly, so learners may need to listen to certain parts more than once at first. If your English is near B2/C1, this can be useful practice, especially if you start with English subtitles.
