3 Best Foreign Registration Services (2026)
The shortlist
1. Mainstay Filing: best for one price nationwide
Mainstay Filing is first on the report card. The reason: $199 on top of the state fee in any state, and the first agent year costs nothing.
A student based in North Carolina would save $100 over three years with North Carolina Registered Agent.co, though that plan stops at the state line.
What the price covers
- Your registration is filed for you
- The registered agent is free in year one
- One service fee in every state
Marks in its favor
- The same $199 price in every state
- Then $149 yearly
Where it loses points
- More expensive than a local service
2. North Carolina Registered Agent.co: best for North Carolina businesses
North Carolina Registered Agent.co is graded second: $199 beyond the state fee to register in North Carolina, with the agent covered in year one.
North Carolina is the one state it covers, so a second state calls for a second provider.
