can i come to US if my visa is not expired yet?

If you have a visa which is valid until June 2014, you are allowed to enter the US during the period of its validity. I do note that you will be inspected by Customs and Border Protection and you will have to show that your intention to come to the US is consistent with the visa. For example, if you have a visitor's visa and have been in the US for most of the past year, there might be concern that you are abusing the visa and that instead of visiting here, you are actually visiting the Ukraine. However, if you have been properly using the visa, you should have no problems with your entry. yeah and what is in it and what I'm fineDue to the limitations of the Lawyers.com Forums, Alan Lee, Esq.'s (the "Firm") participation in responding to questions posted herein does not constitute legal advice, nor legal representation of the person or entity posting a question.
