1. Denomination: Presbyterian (PCK, Hapdong, Tonghap), Methodist, Baptist, Pentecostal, etc.
2. Language: Korean-only services / English Ministry (EM) alongside / English children's ministry
3. Size: 30–80 person home-style, 200–500 mid-size, 1,000+ large
4. Programs: children, youth, young adult, new-family
5. Drive time: 15 minutes is most families' comfort limit

A first-six-weeks plan

1. Week 1: Shortlist 3–5 churches in your city and adjacent cities. Check the website for denomination, Sunday service times, and children's ministry status.
2. Weeks 2–3: Attend services in person. Compare worship style, sermon style, and how visitors are welcomed.
3. Week 4: Register through the new-family ministry at the top 1–2 churches.
4. Weeks 5–6: If you have children, request a brief meeting with the children's or youth ministry coordinator — that conversation usually anchors whether the whole family settles in.

Most Korean-American churches are Protestant, but the Catholic Korean community is meaningful. Key Korean Catholic Masses in OC:
