There is literally an Indian Student Association in my university, there are also student associations for Latin Americans, Indonesians, etc. And then for science-related faculties, the ratio of internationals to Dutch students is about 2:1, which is why English is encouraged.

Try looking for PhDs in the Netherlands. The NL PhD salary is higher than German PhDs and the people are much more open to speaking in English (speaking from experience since I’m a non-EU PhD in NL who did short-term exchanges in DE). They’re much more friendly here especially in university cities.
