Places in America where a immigrant group is associated with

Slovenes in Pueblo, CO

Cape Verdeans: New Bedford, MA

Brockton also has a major Cape Verdean population, as well as Angolan.

Decent number of Cape Verdeans in Boston too. That whole southeastern part of New England is the epicenter of Lusophone immigration to the US.

Here's an old thread on this topic.

North Carolina doesn't have any particularly huge or surprising immigrant enclaves--it has little history of immigration after the colonial period, and then relatively less than other New South cities since much of its growth is various mid-sized strong performers rather than the large cosmopolitan cities which conventionally attract immigrants historically.

Much of the present immigrant diversity is from the Triangle's tech-heavy economy attracting skilled immigrants, the large agricultural and meatpacking sectors in the rural half of the state, and refugee resettlement (or secondary migration in the case of the Hmong.)

Haitians: Mount Olive (work in the Pickle industry)
Hmong: The Unifour area, particularly rural Burke County
Indians: Morrisville and the general area near RTP
Karen: Carrboro
Mexicans: Decent sized populations in most cities, like the rest of the country, but large population working in ag related industries in rural towns, such as Siler City, Asheboro, Sampson County, etc. Robbins in Moore County is majority Latino. Similar distribution for Central Americans but skews more rural IIRC.
Montagnards (Degar): Greensboro, which has the largest Montagnard community outside Vietnam. Decently large communities in other NC cities too.
Moravians: Historically a significant community in the western part of the state, and founded the Salem of Winston-Salem. Cultural identity has fallen away but the Moravian church is decently large.

Finns, Fitchburg Massachusetts. Mainly historical, but it used to be important.

I've always associated Fiinns with northern minnesota

The historic pattern of Finnish immigration to the US is kind of interesting in that it doesn't really track with other Scandinavian immigration patterns in the same way--there's some in the agricultural upper Midwest to be sure but it more closely parallels historic heavy industry. That's certainly true of Northern MN/WI/ and the UP, which is historically the biggest stronghold, but there was a big Finnish presence in Ashtabula, Fitchburg, Western MT, etc. Those resulting union ties, along with a tendency for new immigrants to have been on the red side of the Civil War, meant that Finnish demographics was strongly correlated with far-left, at times communist politics.

(There was a Finnish-language Communist newspaper based in Hancock and Superior which was published until the late 90s!)

Vietnamese: entire West Coast + Gulf Coast- particularly SoCal (Orange County), Bay Area (Santa Clara County), and Metro Houston- but also Nebraska, Atlanta, and Boston

Something which I found out recently is that in addition to the unsurprisingly large community along the Buford Highway, there's a sizable Vietnamese community in along Jonesboro Road in northern Clayton County. Morrow is around 30% Asian, nearly as Asian-American as Johns Creek.

Basques: Boise, ID
Samoans: Salt Lake City, UT
Tongans: Salt Lake City, UT

Much less known but another place with a large Tongan community I learnt about a while ago is Euless, TX (a suburb of Dallas).

Also quite Nepalese too apparently.
