How the Raw Value Is Calculated

The raw value is a legal category: allowed, restricted or not allowed. It measures whether a country generally permits acquiring or keeping a second citizenship.

The rating distinguishes broad acceptance, restricted acceptance with important exceptions and broad non-acceptance. Additional reductions are possible when the rule only applies to certain groups, depends heavily on discretionary approval or is applied uncertainly in practice.

More legal openness is better. Clear and durable dual citizenship matters strongly for migrants because it affects return rights, family planning, travel freedom and long-term security. Especially open rules reach 100 points; very strict non-acceptance can fall to 0 points.
