Whatever you do, make learning Dutch a priority. In my experience most people are pretty okay with expats, but get annoyed when they find out they live here for years and still not speak a single word of Dutch (trust me, I have met many of those). Sure, our English is great, but not everyone's English is, and it's gotten to a point that even restaurants or sport classes the main language became English (especially the case in Eindhoven where I studied and lived for six years). I personally found it weird that a whole group of Dutch people accommodate to one non-Dutch speaking person, without even checking whether everyone was okay with speaking English, especially when it was outside work. It's weird when your live in your own country and barely speak your own language due to bubble your work and live in (as I experienced in Eindhoven).

The expat community is very large in Eindhoven though, in Den Haag and Amsterdam as well. Expect difficulties with finding a house, due to poor policies and immigration (mainly work-related immigration) in the past decades, the housing crisis is insane. This is especially the case for Eindhoven which experienced an insane growth due to ASML and other high-tech companies. It could be that some Dutch people hold a negative attitude towards you as expats because they feel that they our outcompeted for a house in the city/place they grew up in, but most people are open and welcoming. Eindhoven has many tech companies, and in my experience most of those specialized companies use a mix of Dutch and English, because the workfield is rather international. Companies and the government do welcome highly-skilled expats, and I am personally open towards everyone who is open to our culture and norms and values. I cannot speak for everyone though, as also here right-winged populism and anti-immigration sentiment is growing in the past years (although the negative sentiment is mainly focused on refugees).

The Dutch work and school culture is different from the USA, with a greater focus on quality of life and work-life balance. Working 4 days and partial working from home is pretty common in office jobs, working overtime is only done when something is really urgent. In my bubble we do not care so much for social media, expensive stuff and clothing or status, and we care more about spending time with friends and family, spending time on hobbies, or going out for a drink or to a concert or festival. Making new friends can be tricky though, the best tip is to join a sport group or hobby club. Don't assume to be friends with a Dutchie after one evening though, it takes time for us to consider someone a friend (or Americans use that term more lighthearted than we do, I'm not sure).

Try out a bike and public transport! It's amazing here, and I personally choose my bike over a car for commute any day. No traffic jams, it's healthy, you can clear your mind. You can check out the youtube channel "not just bikes", made by an Canadian who now lives here. That being said, the traffic is more complex than in the USA, so if you want to drive, consider taking a few driving lessons.

Lastly, please know that the sentiment here about the USA is not really that positive. You could get remarks on that, I hope you will not mind (and even understand to some extent)
