Ukrainian citizens do not require a visa to visit Antigua and Barbuda.

Under S.I. 31/1996, Ukrainian citizens are exempt from the requirement to possess a visa to visit Antigua and Barbuda, for visits up to six months in duration, provided that they have an onward or return ticket, confirmation of accommodation, and can provide evidence of their ability to maintain themselves in Antigua and Barbuda.
