London Area Expat Groups?

If another thread on this exists elsewhere, please direct me, but I could not immediately find one.

Wondering what, if any, expat groups any of you London-based people belong to. I see tons pop up on Facebook and Meetup, but it's so hard to know which I should consider throwing myself into. Would love any recs! I am SW London based, but up for exploring other parts of town and do not want to restrict myself geographically (yet).

Settling in, holiday prep, and job searching has been occupying much of my time, but I have an eye on the January lull and dark days and want to start getting myself involved in some things to stave off boredom, homesickness, seasonal depression, etc etc.

If you ever feel like venturing outside of London to the Reading area, we have this meetup group going: https://www.facebook.com/groups/1476203412683889/

I belong to American Expats in London and Americans in London FB groups. They’re a good resource for pretty much everything. I live in North London, but I know there are several groups for different areas of the city, too! Hope that helps
