21 CBI
US Air Force veteran. LL.M. in European and Comparative Law, University of Malta. 12 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: $90,000 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. BTC, Lightning, and USDT are our payment rails. Credit cards and bank transfers also accepted as needed. Our advisory fees are payable in any of those. Most government fees settle in local fiat, and we handle that conversion on your behalf with full transparency. El Salvador is the exception: its government contribution settles in BTC or USDT by program rule, never fiat.
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 firm is built and run by Adam Juchniewicz, CEO, 21 CBI: retired US Air Force veteran, LL.M. in European and Comparative Law from the University of Malta, 12 years 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, and 21 CBI practices exactly one discipline: Bitcoin citizenship, advised end to end. Citizens, not tourists.
Yes. Every program we offer is a fully authorized, government-operated route to citizenship. Vanuatu, São Tomé & Príncipe, Türkiye, and El Salvador have established CBI programs through legislation to attract foreign investment; Argentina is a residency-to-citizenship pathway under Law 25,871 and Law 346 Article 2. 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.
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.
Generally, no. Most countries, including the United States, permit dual citizenship; acquiring a CBI passport does not automatically trigger any notification to your home country or affect your existing citizenship status. Rules vary by jurisdiction. During your consultation we walk you through any country-specific considerations relevant to your situation.
That is Exitly. Renunciation requires a second citizenship in hand before the State Department will process the Certificate of Loss of Nationality (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.
