After reading the various posts on this subject and since I am going there next month, I e-mailed the Ukrainian Embassy and received the following reply:
My e-mail to the Embassy:
I am planning to visit Ukraine in late September for about two
weeks to visit my wife's family. I have not visited Ukraine in two years. Under the recent decree by President Yushenko, am I required to obtain a visa for this visit? I am not sure what the language "in transit" means in the President's visa decree. Thank you for your assistance.
Embassy Response:
if your stay in Ukraine doesnt exceed 90 days during 6 months period, visa is not requied
