The local and foreign physical persons can import an unlimited amount of levs and foreign currency cash. When the amount of the imported money is up to 8000 levs or their equivalent in another currency they are not declared in writing and the travellers can walk through the "green channel" which means that the person has nothing to declare.

When the amount of the imported money is over 8000 levs one has to fill out a currency customs declaration for the purpose of their being declared to the customs authorities with the travellers obligatorily walking through the “red channel”.

The local and foreign physical persons can export levs and foreign currency cash amounting to up to 8000 levs or their equivalent in a foreign currency without having to declare that in writing, and they can walk through a “green channel”.
If the amount is from 8000 to 25000 levs it should be declared in writing in a currency customs declaration.

When the amount of the money exceeds 25000 levs or their equivalent in a foreign currency the manner of acquiring the money is entered and a certificate from the tax administration must be presented that the person does not have any overdue tax liabilities, and its number is entered into the currency customs declaration.
