Traveling with a biometric passport
In 2019, the British passport is ranked fifth in the ranking of the most powerful passports in the world. It has a total of 165 countries accessible (meaning you can visit them without a visa or thanks to an easy visa procedure). Most of the time, the traveler is allowed to stay in the country for 90 days, except if they have a special visa (a work visa for example).
When you plan to travel, be sure that the date of validity of your passport will be enough. Some countries, such as Australia, Bolivia, Brazil or China, require a period of validity of the passport that runs at least 6 months after the date you return from your stay. Your travel document is really valuable: it is important to take care of it (entering some countries can be complicated if the document cover is damaged.) and to always keep paper or digital copies with you.
