Guinea-Bissau Dual Citizenship in the U.S. — 2026

Data last verified: September 2026 — take qualified advice on any individual case.

Bissau-Guinean nationality runs by descent, and the country has generally accepted that its nationals hold other citizenships — a diaspora concentrated in Portugal, France and Senegal makes that a practical necessity. The obstacle here is not the rule but the absence of any consular authority in the United States to document it.

Quick facts

BasisDescent

ObstacleNo consulate to document it

Membership of the Community of Portuguese-Speaking Countries matters more than it might appear: it shapes where the diaspora goes, where the working embassies are, and which country’s mission is likely to be able to help.

Anyone whose position in the United States is unresolved should take immigration advice before approaching any authority of their country. It costs a consultation and can matter a great deal.

What to do

  1. Take immigration advice first if your position here is unresolved.
  2. Gather every Bissau-Guinean document the family holds.
  3. Write to the Permanent Mission in New York and ask what it can do.
  4. Ask whether a Bissau-Guinean embassy elsewhere could handle your file.
  5. Establish the children’s position alongside your own.
  6. Take local legal advice on land and inheritance.

Documents to gather

Where to enquire

At the Permanent Mission to the United Nations in New York; decisions rest with the authorities in Guinea-Bissau.

Additional notes

Keep expired documents

Where there is no consulate to verify anything, an old passport may be the best evidence you have.

Lisbon is worth asking

The embassy in Portugal serves a large community and is fully operational.

Children

Their position follows the parents’ documented status, so secure the parents’ records first.

Take proper advice

A lawyer familiar with Bissau-Guinean law is the right source for anything consequential.
