Sanctuary DMV as you mentioned. Also, Lutheran Social Services North Capitol Area works with refugee populations. Remember they were at the forefront coordinating services and housing for individuals fleeing Afghanistan.

Might be nice to see the local buy nothing groups partner with some of these groups. However I know there are a lot of challenges with used and worn goods.

Know some people personally that are recent immigrants/migrants that have been helped by the variety of groups in the area (think Hyattsville might have a high concerning?). Just wish I could remember all the different charity and org names. Hopefully this thread gets bigger as anecdotally these groups have real lasting impact.
