Being from Jamaica doesn't mean anything, I'm also an immigrant here.

There are numerous factors that will affect your ability to finance real estate in the US, such as the restrictions of your home country, immigration status, your personal financial history, etc. 

Phoenix has seen incredible amounts of immigration in the past few years, with that comes the need for new housing.

Also GC I know, San Diego: "I pay $50/hr for someone that shovels dirt, immigration status be damned."

Trump just banned immigration.

However I take comfort knowing rental vacancy rates across the country are at historic lows and inventory remains incredibly low, while immigration remains strong. 

All those immigrants who wanted to buy and are still renting will just continue to rent..

Are they foreigners/immigrants?

MAGA will most likely throw off more government restrictions and further limit immigration that takes US jobs.The economy (jobs) has stumbled not died, and it will get back up--people just need to be able to eat until then.Most (but not all) people have some safety net, friends family, church efforts, etc...America can handle this.

Highly disagree with you and agree with Shiloh.If intelligence and willpower weren't the main difference between being rich and being poor, we wouldn't be hearing about the success of immigrants from Communist Russia, communist China, Israel, etc. who came from poverty, harsh conditions, etc. only to find success in the USA.Go ahead and read 'The Millionaire Next Door'.
