For whatever it's worth, I'm treated this way as a white American. I'm selected for extra screening every single time I reenter the country. Though, I don't think it's ever been longer that 30 minutes or so. I don't know why but some combination of having a beard, being naturally anxious and having traveled to "unusual" countries -- at least by American standards. Crossing the border makes for a guaranteed panic attack and I've let my passport expire. It's a damn shame, too, because it's depriving my kids of invaluable life experiences and has brought my relationship with my spouse (who loves to travel) to the brink on multiple occasions.
US Border control is always worse than any EU-country (as a white EU-resident I might add). We have lots of umlauts in our names äöå etc. which can seriously mess up you ESTA or travel booking unless you double and triple check :)
But still India had the absolute worst border control I've ever experienced. I probably rather sleep on a cold prison floor a couple of days than having to manually reenter all my information eight times!
I mean, as US citizen I find my interactions with CBP to be easy but it’s because their options are admit me or arrest me vs German guard who questioned me for 15 minutes if my personal laptop was because I was planning on working. Anytime you are entering a country you have right to be in, it’s generally easier.
