They're living in my property-- I have to know who they are.Maybe they're an illegal immigrant, but even then, not listing a birthday?

Be sure they are paying in your local currency.For lower income immigrants, making a permanent move here, they typically offer up a license or new SS# but have NO savings, new job, living with relatives, no references, etc.

Didn’t we already have the immigration debate in another thread?

When you are new to the US there are different immigration status that you could have.  

As a first generation immigrant, I had to re-learn everything that I was taught.

Donut shop is usually a specific immigrant's family business tradition, that's why it's so niche and hard to enter, similar to Milk Tea shop or Taqueria.But I'm wondering rather than investing in endless multifamily syndication, why I can't just invest to a milk tea shop in front of my home LOL maybe in the future there would be more opportunities to have this gap to be recognized.

I have yet another friend in Squirrel Hill, Pittsburgh who is a Russian-Jewish refugee and he rents rooms and apartments almost exclusively to Pittsburgh's burgeoning immigrant former Soviet-Union community.

What's also interesting is that we found out from searching online that the Realtor and the owners are of the same immigrant background and are also friends on Facebook.

Oh, and Broadway used to be nice when the immigrants (like my parents) lived there in the 60s.

We ended up renting to a couple of guys, recent immigrants with poor English skills that we had to communicate with via a translator.
