Most citizenship by investment programmes let you keep your existing nationality. The harder question is usually whether your current country allows you to hold a second citizenship.

Whether you can hold dual citizenship depends on two separate rules. First, does the new country allow new citizens to keep their old nationality. Second, does your current country allow its citizens to take another nationality without losing the first.
A programme can welcome dual citizenship while your home country still forbids it. Always check both sides before you apply.
Caribbean citizenship by investment programmes, including those run by St Kitts and Nevis, Dominica, Grenada, Antigua and Barbuda, and Saint Lucia, generally allow you to keep your existing nationality. Each programme is run by a national Citizenship by Investment Unit.
Several other routes also permit dual citizenship, including Malta, Turkey and the discretionary Austrian route. Naturalisation in countries such as Portugal can also allow a second nationality. Rules and conditions change, so confirm the current position with the official authority.
Some countries restrict or do not recognise dual citizenship for their own nationals. People from those countries may have to renounce, or may automatically lose their original citizenship when they naturalise elsewhere.
Because these rules differ widely and change over time, do not assume. Verify your home country's nationality law with its official authority, and take licensed advice before acting.
Ask whether the programme requires you to ever reside, whether children and a spouse can be included, and whether the second citizenship must be declared at home. These details affect whether dual citizenship works in practice for your family.
If you want a route that protects your current passport, a vetted advisor can help you shortlist programmes that fit your nationality and goals.
Not by itself in many cases, but some countries automatically withdraw their citizenship when a national acquires another. The deciding rule is your current country's nationality law, which you should confirm with its official authority.
Some countries require you to declare a second nationality and some do not. Check your home country's rules with the official authority.
Many programmes allow a spouse and dependent children to be included, but each person is still subject to their own home country rules. Confirm the details for your family before applying.
