South Sudan Dual Citizenship in the U.S. โ€” 2026 Guide

Checked September 2026. This page was written for this country and its details were checked against the authorityโ€™s own sources that month. Consular rules still change without notice, so confirm anything that will cost you a journey or a fee with the office that covers you. How we check our data.

South Sudan’s nationality law permits citizens to hold another nationality, and nationality itself runs through descent and origin: having a parent, grandparent or great-grandparent belonging to one of the country’s indigenous communities. That ancestral basis is unusual and matters for families documenting a claim.

Because the claim can rest on a grandparent or great-grandparent, family knowledge matters as much as paperwork, and older relatives are often the best source before anyone approaches a consular counter.

Anyone whose own position in the United States is unresolved should take immigration advice before approaching any consular authority. That is sound practice generally and matters more where conditions at home are difficult.

What to do

  1. Take immigration advice first if your position here is unresolved.
  2. Establish through family which ancestor grounds the claim.
  3. Gather every document the family holds, whatever its origin.
  4. Write to the consular section explaining the position.
  5. Document the children alongside the adults.
  6. Take separate advice on land and inheritance.

Required documents

Where to apply

At the embassy in Washington; decisions rest with the authorities in South Sudan.

No offices currently listed.

Additional notes

Ask the elders first

Where a claim rests on a grandparent or great-grandparent, family knowledge is the starting point and is not written down anywhere else.

Advice first where status is unresolved

An immigration lawyer is the right person to ask before any step involving your country’s authorities.

Community land

Most land is held by communities rather than individuals, so inheritance questions involve more than a title document.

Take proper advice

A lawyer familiar with South Sudanese law is the right source for anything consequential.
