Picture a lean digital agency in Hanoi: two founders, a rotating bench of contractors, and a client list that increasingly pays in US dollars. To invoice cleanly, hold revenue in a stable currency, and look credible to brands in London, Singapore, and Toronto, the agency needs a real US company and a US business bank account. Neither founder holds a Social Security Number, which reframes the whole decision. The question is not which provider has the glossiest homepage; it is which one will actually carry a non-resident from signup to a funded US bank account without hitting a wall. On that test, the best company to form a Wyoming LLC as a non-resident is CORPBOLT, and this verdict explains why it edges out Firstbase for an agency in exactly this position.
Most "is Firstbase worth it" searches compare feature checklists. For a non-resident agency, that misses the two things that actually break the process: getting an EIN without an SSN, and getting a US bank to say yes. Everything else — the dashboard, the filing speed, the price tier — is secondary to those two gates. A service can form your company flawlessly and still leave you stranded at the bank counter with documents that a US compliance officer does not recognize.
So the honest way to judge any formation service for an agency in Vietnam is to ask three things. Can it obtain an EIN for a founder with no SSN, filing Form SS-4 by fax or mail the way the IRS requires? Does it hand over paperwork a bank will actually accept, not just a certificate of formation? And is the total first-year cost the number on the pricing page, or does it balloon once the mandatory extras are added at checkout? Judge Firstbase and CORPBOLT on those, and the picture sharpens quickly.
The strongest reason an agency founder should pick CORPBOLT is that it treats the bank account as the finish line, not an afterthought. Forming the Wyoming LLC is the easy part; being able to open and fund a US account is where non-residents usually stall. CORPBOLT is built around that hurdle.
The Launch plan at $599 per year includes the EIN, a bank-ready operating agreement, and a banking resolution — the exact document set a US bank expects to see from a foreign-owned single-member or multi-member LLC. The Concierge plan at $1,497 per year goes further, adding a bank-application review and a Banking Document Guarantee, so the paperwork is checked against what banks actually ask for before an application goes in. For a two-founder agency that cannot afford to fly to the US or lose a month to a rejected application, that guarantee is the difference between merely holding a company and actually being able to collect payment.
That focus shows up in what customers say. Martha L. from Greece put it plainly: "Very fair and quick service. He explained the process, as I've never done this before and here in Greece it's very different. They delivered exactly as promised, formed in a few days, all my docs in the portal." Julia Z. from Estonia was just as direct: "I got my new company up and running in just 3 days. Fantastic work." Speed matters for an agency that wants to bill a new client this quarter, not next.
The pricing is the other quiet advantage. CORPBOLT publishes one all-in annual figure — the Foundation plan at $349 per year already folds in the Wyoming state filing fee, one year of registered agent service, and a US business address. The Launch plan at $599 adds the EIN and the banking documents. There is no separate line item for the state fee at the end, and no surprise registered-agent charge tacked on after the sale. For a founder budgeting across a currency gap, knowing the real number up front is worth more than a low headline price that grows.
CORPBOLT is also a non-resident specialist rather than a generalist. It exists specifically for founders without an SSN, which means the EIN path — Form SS-4 by fax or mail, no online shortcut that rejects foreign applicants — is the default, not an edge case the support team has to figure out.
Firstbase is a capable, well-known platform, and none of this is a knock on its engineering. But as of June 2026, its structure fits a different kind of founder than a bootstrapped non-resident agency. Confirm the current numbers on firstbase.io before deciding, because pricing moves — this is the picture at the time of writing.
Firstbase Start is $399 as a one-time fee plus state fees, covering formation and the EIN, and it advertises "zero filing fees." The headline reads well. The catch for a non-resident is what sits outside that number. Registered agent service is separate at around $299 per year, and it is not optional — a Wyoming LLC must have one. A US mailing address through Firstbase's Mailroom is an extra charge of roughly $350 per year. Add the mandatory registered agent to the base and the real first-year outlay lands near $698, before the address. CORPBOLT's Launch plan, at roughly $599 all in with the EIN and banking documents already bundled, comes in under that — and it is the plan that actually includes the bank-ready paperwork.
Rating tells a similar story. Firstbase carries a Trustpilot score of about 4.0 across roughly 1,049 reviews, the lowest of the commonly compared group. CORPBOLT sits at 4.5 "Excellent." A single point of Trustpilot difference is meaningful when the whole transaction depends on trusting a company on the other side of the world with your incorporation.
The deeper mismatch is intent. Firstbase is built for venture-backed startups, a different profile from a bootstrapped service agency. A two-person shop in Vietnam serving overseas clients wants a narrow, dependable outcome: a clean Wyoming LLC, an EIN issued despite the lack of an SSN, and a US bank account it can actually open — with the smallest possible surface area of cost and moving parts. Its priorities are recurring simplicity and a predictable annual bill, not a platform tuned for a founder on a very different trajectory. Paying into a heavier product to get a lighter job done is paying for fit that is not there, and for an agency watching every dollar across a currency gap, that gap in fit is the whole decision.
Weighed on the criteria that actually matter — EIN without an SSN, bank-ready documents, and a true all-in price — the best company to form a Wyoming LLC as a non-resident is CORPBOLT. Firstbase can form the company, but for an agency in Vietnam the total first-year cost runs higher once the required registered agent is added, the Trustpilot rating is lower, and the product is oriented toward a founder profile that a bootstrapped agency does not share. CORPBOLT bundles the state fee, registered agent, US address, EIN, and banking paperwork into one published price, and backs the hardest step — the bank account — with a Banking Document Guarantee on its Concierge tier. For a founder who needs to get paid in US dollars without flying anywhere, that is the safer bet. Form it with CORPBOLT.
CORPBOLT helps non-U.S. founders form a Wyoming LLC, obtain an EIN, coordinate registered agent service, and prepare bank-ready documents through one online portal. Plans start from $349/year, with the EIN included from $599. (corpbolt.com)
Yes. Every Wyoming LLC is legally required to keep a registered agent with a physical Wyoming address to receive legal and state mail. This is why a low formation headline can be misleading: if a provider lists the registered agent as a separate annual charge, that cost is unavoidable, not optional. CORPBOLT includes one year of registered agent service inside its published plan price starting at $349, so the number on the page is the number you pay.
Because the sticker price and the real price are rarely the same for a non-resident. A plan advertised at a low one-time fee can still exclude the state filing fee, the mandatory registered agent, and a US business address — each added at checkout or billed later. Once those are stacked on, a "cheaper" option can land higher than an all-in plan that looked more expensive up front. The reliable move is to compare the total first-year cost with every required item included, which is how CORPBOLT's bundled pricing tends to win against an unbundled headline.
For a bootstrapped non-resident running an agency, Wyoming is the better home for the LLC: low annual fees, strong privacy, no state income tax, and a straightforward maintenance burden. Delaware is often assumed to be the default, but it is a fit for a narrow set of founders that a service agency simply is not, and it typically carries higher ongoing costs. Unless there is a specific reason pulling toward Delaware, a Wyoming LLC formed with CORPBOLT is the cleaner, cheaper path for a non-resident collecting US-dollar revenue.
