Meeting people who share your language and food can make the first months much easier. They also know the local tricks: which store sells your spices, which doctor speaks your language, which landlord is fair.
Where to look, step by step
Search your map app for your country or language plus words like "association", "community center", "grocery", "restaurant", "temple", "church", "mosque" or "gurdwara". Example: "Nepali grocery", "Ethiopian church", "Bangladeshi association".
Visit a home-country grocery store or restaurant. Look at the notice board by the door for events, rooms for rent, language classes and tutors. Ask the owner which groups are active.
Go to a place of worship during a main service or festival. Many have newcomer help, food and youth groups. See Places of worship, community groups and volunteering.
Search Facebook, WhatsApp, Telegram or WeChat for "[your country] in [your city]". Ask an existing member to add you.
Students: your university likely has a student association for your country, plus an international student club. Their first events of the year are the easiest time to join.
Your embassy or consulate may list community organizations and post cultural events.
Professional groups: many fields have associations of engineers, doctors or nurses from your country or region.
Meetup and Eventbrite list cultural evenings, dance classes, sports and language exchanges.
Community groups often celebrate national days and religious festivals with big events. Going once is a fast way to meet many people at the same time.
Weekend language and culture schools teach children your home language.
Parent WhatsApp groups share babysitting, school tips and used children's items.
Building beyond your community
Your diaspora is a great base. Also join one group with mostly Americans or people from other countries: a sports team, a volunteer group, a class. It improves your English and grows your network for jobs.
Staying safe in community groups
Most help is genuine. Still, newcomers are a common target of scams inside their own community: fake rentals, "immigration consultants", job offers that require fees, and investment groups.
Do not post or send copies of your passport, visa or I-94 in group chats.
Get legal immigration advice only from a lawyer or a DOJ-accredited representative. See Finding real legal help (and avoiding notarios).
Do not borrow from or lend large amounts to people you just met.
Waiting for the community to find you. Go first; most groups are glad to welcome you.
Trusting someone's immigration or tax advice because they share your language.
