A U.S. LLC set up from Switzerland still comes with an operating agreement, ownership paperwork, a notarized Form 1583 for its mailing address, and often a request from a Swiss bank for proof of who owns the company. The state filing rarely causes the delay; the documents around it do.
Why a founder in Switzerland sets up a U.S. LLC
Founders based in Zurich, Geneva, Lausanne or Lugano often open a U.S. LLC to bill American clients without going through a Swiss entity, hold funds in dollars, or run a product aimed squarely at the U.S. market. TR Signing Group does not advise on how the LLC should be reported or taxed in Switzerland: that stays with your treuhänder, fiduciaire or attorney.
TRSG steps in once the documents are drafted and need to be signed, notarized or authenticated in a way a Swiss bank will accept without sending the file back.
The company documents that follow the filing
Once the LLC exists, a bank or partner typically asks for:
- Operating agreement. The internal rulebook of the LLC, requested even for a single founder.
- Membership certificate. States who holds the company. TRSG's guide on documents for a Wyoming LLC held by a non-resident is a useful companion if your LLC was formed in Wyoming rather than another state.
- Ownership declaration or resolution. Confirms who can sign and open accounts. Swiss banks in particular tend to compare this against every other document in the file.
TRSG executes these corporate and ownership documents so the founder's name is spelled the same way on every page, including accents, which matters more with Swiss compliance checks than with most other recipients.
Form 1583 and a U.S. mailing address
Most founders in Switzerland also need a U.S. mailing address through a virtual mailbox, which requires a notarized Form 1583 with two forms of identification under USPS rules before the provider can accept mail for the company. TRSG's guide to Form 1583 from Switzerland covers what identification tends to work across French, German and Italian speaking cantons. TRSG executes the notarization itself through Form 1583 notarization for virtual mailboxes.
Swiss banks tend to ask twice: keeping names consistent
A compliance officer at a Swiss bank will often cross check the operating agreement, the membership certificate, the resolution and the passport name, and send the file back over a detail as small as a missing middle name or a different spelling of a canton address. There is no general list that covers every bank, so the safest step is to ask the specific institution what it wants in writing, then execute everything to match before sending it over.
Executing documents between Switzerland and the U.S. East Coast
Signing happens one of three ways: a recorded online notarization session for documents a recipient accepts electronically, wet ink on a printed original mailed or couriered when paper is required, or coordination with a co-founder or manager already in the United States. Evenings in Switzerland generally overlap with daytime on the East Coast, which leaves enough room to book a session without anyone staying up through the night.
It is worth sending each founder a single packet listing exactly which page needs a signature and which needs a notarization, rather than letting everyone work from a different copy of the same file. A Swiss compliance officer comparing two founders' documents is more likely to flag an inconsistency than approve a close match, so a shared packet with one source document for each item is the safer approach.
Co-founders split across two cantons
When one founder is based in Geneva and another in Zurich, the paperwork has to satisfy a bank that reads documents in French and German without noticing any gap between the founders' files. Each founder typically signs a separate identification page and, if the mailbox is shared, a separate Form 1583 session, while the operating agreement and the membership certificate stay identical for both. Keeping one master version of each document and distributing it for signature, rather than letting each founder draft a personal copy, is what keeps the names and dates consistent.
How TR Signing Group handles it
TR Signing Group is set up in Bayonne, New Jersey, and takes on files of every size, from a single notarized signature to a complete international package. For a founder coming out of Switzerland, TRSG coordinates with your formation provider and executes what the bank asks for: notarization in person or online, wet ink where it is required, apostille, scanning and tracked shipping. The full scope is described on the U.S. LLC support page for foreign founders. Once your bank has specified what it needs, request a quote and TRSG will confirm what it can take on.

Questions we hear often
Is it possible to complete every signature without visiting the United States?
In most cases yes, through an online notarization session or a wet ink original that gets shipped. Some Swiss banks still prefer the paper version.
Why does a Swiss bank keep returning the same file?
Usually because one document does not match another exactly, often a name spelled slightly differently. Lining up every document before sending it tends to fix this.
What has to match across the documents for a Swiss compliance check?
Names, including accents, and addresses should read identically on the operating agreement, the certificate and any resolution. A single inconsistency is often enough to trigger a request for correction.
Who decides which canton address appears on the paperwork?
You or your bank, not TR Signing Group. TRSG executes whatever address and wording it is given.
Does a Swiss bank always require an apostille?
No, it depends on the bank and the specific document. Ask the institution for its own list first.
