How to travel with two passports?

Having received a second citizenship, many people have a question, how to use a new passport and how to cross the border with two passports?

When traveling with two passports, the following must be considered:
• When entering a country, you must use the passport of the country whose citizenship you have. For example, if you have citizenship of Grenada and Russia, then you need to use a Grenada passport to enter Grenada, and a Russian passport to enter Russia.
• When leaving and entering from any country, you must use the same passport. You cannot enter a country as a citizen of one country and leave it as a citizen of another state. However, this rule does not apply to cases of a change in migratory status, for example, from a tourist to a resident or citizen.
• When buying a ticket, it is recommended to use the document that is most suitable for entering the country of destination. Check-in for a flight and passport control at the airport are independent of each other, so you can check-in for a flight with one passport, and go through passport control with another.
• If you are traveling to other countries, we recommend using the passport that is more suitable for your particular situation and allows you to enter that country. With a Grenadian passport, you can visit 180+ countries without a visa, including the UK, the EU, China and most Commonwealth of Nations countries.

Example: if you are traveling to an EU country, you can use a passport to leave Russia and a Grenadian passport to enter the EU, as it allows visa-free entry. When traveling in Europe, it may be sufficient to use only a Grenadian passport and set aside the Russian one until you return to Russia.
