TransferWise, an international money transfer app, was founded by immigrants and is dedicated to "fostering a more inviting global community." By studying and rating nine factors that influence how welcoming a city is towards immigrants, TransferWise was able to rank the 50 most populous U.S. cities on their ability to draw in and sustain immigrant populations.
San Francisco, California, snagged the #1 spot.
The city has easily established itself as a bastion for immigrants due to its municipal ID programs, sanctuary city status, and public transit (which may be less omnipresent than those in Chicago and New York, but is also cheaper). The city's only major detractor as a home for immigrants is its cost of living: it's 62.6% higher than the U.S. average. However, Mayor Ed Lee has pledged to create 30,000 new, affordable homes by 2020. As of the writing of this article, he's already created 17,000.
