US Air Force veteran. LL.M. in European and Comparative Law, University of Malta. 10+ years at the US Department of Homeland Security on immigration policy. Stacking sats since 2020. Clients across four continents.
“I’d been quoted by three different firms before finding 21 CBI. Two of them couldn’t even tell me whether they’d accept BTC; the third firm wanted me to wire fiat to a bank in Dubai without explaining everything. Adam walked me through the entire Vanuatu timeline on our first call, broke down every fee in sats, and my passport was in hand in under 60 days. For someone running a company, the last thing I need is ambiguity around something this important.”
James R., CTO at a Bitcoin infrastructure company
Vanuatu CBI Client
“I looked at Caribbean programs for months, but every firm I talked to either charged hidden fees or couldn’t explain how source-of-funds worked for on-chain wealth. 21 CBI broke down the entire São Tomé process on our first call: $90K government fee, 5% advisory, Non-CRS, and a CPLP pathway to Portugal. Six weeks later I had my passport. No surprises, no conversion drama, every cost quoted in sats upfront.”
Marcus L., Founder & CEO of a digital assets fund
São Tomé & Príncipe CBI Client
“Every CBI firm I talked to treated my Bitcoin like a compliance headache. 21 CBI was the first to treat it like what it is: how I do business. The Vanuatu process was straightforward; every cost was quoted upfront in sats, and I had my passport in under 60 days. No surprises, no fiat conversion drama, no chasing people for updates. If you’re a Bitcoiner, 21 CBI is the place to get your second passport.”

Our 5% advisory fee is calculated on the government fee or donation amount only, never on the total engagement cost. For example, Vanuatu’s government fee is $130,000, so our advisory fee is $6,500. This covers end-to-end application management, document preparation, government liaison, and post-approval support. There are no hourly rates or hidden markups. You’ll see a full cost breakdown in sats before you commit to anything.
Yes. Bitcoin is our native payment method: on-chain or Lightning, whatever works for your stack. Our advisory fees are payable in BTC as well. Government fees to the respective countries typically settle in fiat, which we handle on your behalf with full transparency. We also accept USDT, fiat, and credit cards for those who need them.
It starts with a confidential inquiry where we assess your goals, budget, and timeline. From there: 1) we recommend the best-fit program, 2) due diligence is completed by the issuing country, 3) you provide the required documents and we prepare your full application, 4) the application is submitted to the government, and 5) upon approval, you receive your citizenship certificate and passport. We manage every step; you stay informed without doing the legwork. Most programs can be completed in 30 days to 6 months, depending on the country program and application volume.
Denial rates for the programs we offer are very low, typically under 1%, because we pre-screen every applicant before submission. If an application is denied, government fees are generally refundable minus a processing charge (which varies by country). We’ll work with you to explore alternative programs if needed. We’ll always be transparent about your likelihood of approval before you commit any funds.
Yes. Every program we offer allows you to include your spouse and dependent children in a single application. Most programs also allow the inclusion of dependent parents. Additional government fees apply per family member. We provide a full family cost breakdown upfront so there are no surprises. Your entire family receives citizenship and passports together.
The standard requirements across most programs include: a valid passport, birth certificate, police clearance certificate, proof of funds, passport-sized photos, and a medical certificate. Some programs require additional documentation such as proof of address or a CV. We provide a detailed checklist tailored to your chosen program and handle all document preparation, notarization guidance, and apostille coordination on your behalf.
The firm is built and run by Adam Juchniewicz, CEO, 21 CBI: US Air Force veteran, LL.M. in European and Comparative Law from the University of Malta, over a decade at the US Department of Homeland Security on immigration policy, and stacking sats since 2020. This is not a firm that "also accepts crypto." It is a firm built by a Bitcoiner, for Bitcoiners. Citizens, not tourists.
Yes. All client communications are conducted over end-to-end encrypted channels (Signal preferred, PGP available). Documents are handled on a compartmentalized, case-by-case basis; your files are never stored on shared cloud platforms or mixed with other client data. We practice minimal data retention: once your passport is delivered and the engagement is closed, sensitive documents are securely purged. We never share client information with third parties beyond the required government submission.
Yes. Every program we offer is a fully authorized, government-operated route to citizenship. Vanuatu, Türkiye, and El Salvador have established CBI programs through legislation to attract foreign investment; Malta operates a discretionary, merit-based naturalisation framework under the Maltese Citizenship Act. The passports issued are standard national passports with full citizenship rights. CBI is used by tens of thousands of individuals globally each year and is recognized by international law.
Several of our programs offer favorable tax treatment for Bitcoin holders. Vanuatu has zero income tax, zero capital gains tax, and zero inheritance tax. El Salvador, the first country to adopt Bitcoin at the national level, offers 0% capital gains on Bitcoin transactions for foreign investors. Türkiye applies 0% capital gains tax on real estate held for more than 5 years; treatment for other asset classes, including cryptocurrency and securities, varies. During your consultation, we can advise on which jurisdiction fits your specific situation and asset profile. Consult a qualified tax advisor regarding your specific situation.
This is one of the most common concerns for Bitcoiners pursuing CBI. 21 CBI prepares on-chain source-of-funds documentation directly. We work with exchange records, transaction histories, mining income documentation, and UTXO-level proof to build a compliant source-of-funds narrative that governments accept. Unlike traditional CBI firms, we do not treat Bitcoin wealth as a red flag. It is our starting point.
Your Bitcoin exposure is locked at the time of payment, not at the time of application submission. Government fees are denominated in USD (or local currency), and we handle the fiat conversion when the payment is due. This means you are not exposed to BTC price volatility during the processing period. We also provide clear timelines so you can plan your payment timing around your own convictions about the market.
A local lawyer in Vanuatu or Türkiye may handle the government submission, but they typically lack multi-jurisdiction expertise, Bitcoin-native workflows, and end-to-end case management. 21 CBI provides strategic guidance on which program fits your specific situation, handles all document preparation across jurisdictions, manages the fiat conversion for government payments, and serves as your single point of contact throughout the entire process. We also advise on tax implications and ongoing jurisdictional strategy beyond the passport itself.
In most cases, no. The majority of countries, including the United States, permit dual citizenship. Acquiring a second passport through a CBI program does not automatically trigger any notification to your home country, and it does not affect your existing citizenship status. However, rules vary by jurisdiction. During your consultation, 21 CBI will advise on any country-specific considerations relevant to your situation.
No. Citizenship by investment programs grant additional citizenship. You are not required to give up your existing nationality. Your new passport is a supplement, not a replacement. You can hold both (or multiple) citizenships simultaneously. Renunciation is a separate, voluntary decision that some clients pursue for tax or strategic reasons, but it is never a requirement of the CBI process itself.
Signal is the default. End-to-end encrypted, no message backups on a third-party server, and the platform itself does not see metadata about who you are messaging. PGP is the second channel, used for documents that require an audit trail or that you want stored as encrypted files rather than messages. Both are offered before the first call; the choice is yours. There is no shared inbox, no ticketing system, and no junior associate. Every message you send reaches Adam directly.
The engagement letter is a four-page document that names the program, the scope of work, the fee structure, and the milestones. You sign it on Signal or by email before any filing work begins. Payment is structured in two parts: the advisory fee plus the per-applicant due-diligence fee on engagement, and the remaining advisory balance plus the government contribution after government approval. Government fees are paid only after the program approves the file, so you are not at risk for the largest line item before the outcome is known. Every cost is quoted in USD and live sats at the time of engagement.
Yes. US persons file FATCA Form 8938 and the FBAR (FinCEN Form 114) for foreign financial accounts above the reporting thresholds, and the IRS already has a documentary trail for any Bitcoin position you have reported on Form 8949 or Schedule D. We use that existing paper trail as the spine of the source-of-funds package: filed returns, exchange Form 1099-B records, and on-chain history that ties exchange withdrawals to your self-custody addresses. The CBI program's due-diligence body wants the same thing the IRS already has on file, presented in a different format. We assemble it. If you have unreported gains or unfiled returns, we will tell you to fix that with a tax attorney before we file the CBI application; we do not paper over compliance gaps.
That is Exitly. Renunciation requires a second citizenship in hand before the State Department will process the CLN, so the typical pipeline is 21 CBI for the new passport, then Exitly for the renunciation. Exitly handles the covered-expatriate analysis, exit-tax modeling, Form 8854, the embassy interview, and post-renunciation banking. The two firms share the same ecosystem and the same encrypted-comms standard, so the handoff is direct. If you are still on the fence about renunciation, the US Exit Tool on this site walks the math before you commit.
Yes. Citizenship stacking is the most common multi-program engagement: speed in one jurisdiction, structure in another. Common pairings include Vanuatu plus São Tomé (fast mobility plus Non-CRS posture), Vanuatu plus Türkiye (speed plus E-2 access to the United States), and Vanuatu plus El Salvador (speed plus Bitcoin-native settlement at the sovereign level). Each program is filed under a separate engagement letter and a separate advisory fee. We sequence the filings so government screening on the second program inherits the documentation already prepared for the first; the document burden does not double.
Yes. The advisory engagement closes when your passport is in hand, but the working relationship does not. Adam stays available on the same Signal thread for passport renewal coordination, dual-citizenship banking questions, and tax-residency check-ins as your situation changes. Many clients return for a second program on the stack 12 to 24 months after the first; some come back five years later for a renewal or a child's inclusion. There is no retainer for ongoing access. The relationship is the product, not the transaction.
