Cabinet of Ministers Resolution No. 884 of 2013, adopted under Article 21 of the Law on the Legal Status of Foreigners, says foreigners must have funds of 20 times Ukraine's monthly subsistence minimum per month, calculated for other lengths of stay as ((20 × the monthly minimum) ÷ 30) × (days of stay + 5). It can be established by cash, a document entitling you to funds from a Ukrainian bank, a payment card with a bank statement, an accommodation booking, a tour voucher, a host's guarantee letter or a return ticket with a fixed date, and is checked by Ukraine's missions when issuing visas, at border checkpoints during second-line control, and by the migration service when extending a stay.
