A clean, complete file is the single biggest factor in how fast your citizenship by investment application moves. Missing or inconsistent documents cause most of the delays we see.
Use this checklist to prepare. Exact requirements vary by country, so your agent should confirm the final list, but this covers what nearly every programme asks for in 2026.
Personal documents (for every applicant)
Family documents

Police and background checks
These take the longest. Some countries need you to apply in person or through an embassy, so start here.

Financial and source of funds

Preparation rules that save weeks
- Names must match everywhere. A missing middle name on one document can stall the file.
- Check validity dates. Police and medical certificates expire. Time them so they are fresh on submission day.
- Apostille or legalise. Documents from Hague Convention countries need an apostille. Others need embassy legalisation.
- Explain gaps. Unexplained employment gaps or large transfers raise questions. Add a short explanatory note.
- Be honest about refusals. Previous visa refusals or name changes must be declared. Due diligence will find them.
What happens after you submit
Due diligence takes most of the processing time, typically 2 to 4 months for the Caribbean. Once approved in principle, you make the investment, take the oath where required, and receive your certificate and passport.

Frequently asked questions
How long does it take to gather the documents?
Usually 4 to 8 weeks. Police certificates from countries you have lived in and apostilles or embassy legalisation are the slowest parts, so start those first.
Do documents need to be translated?
Yes. Anything not in English must be translated by a certified translator, and both the original and the translation usually need to be notarised or apostilled.
What is source of funds?
Proof of where the money for your investment came from, such as salary records, a business sale, property sale, inheritance or dividends. It is the part of the file that most often causes delays.
Is there an interview?
Yes for the Caribbean programmes. The five Eastern Caribbean states agreed in 2024 to make interviews mandatory, and biometrics are now standard.
