In addition to the minimum BTA, Germany and other countries often require people travelling from Nigeria to show evidence of their financial stability and proof of sufficient means to support themselves while in their destination country. This can be done through a combination of different documents and financial records such as:
-Bank statements demonstrating a minimum balance of N35,000 or its equivalent in foreign currency.
-Salary payslip.
-Sponsorship letter from a family member or friend abroad (accompanied with a copy of their passport and resident permit) providing financial support for the trip.
It's important to note that these requirements can change over time and depending on the purpose and duration of the travel. It is advisable to check with the embassy or consulate of the country you're visiting for the most up-to-date information on travel regulations, visa requirements and minimum BTA.
