In many threads here, this question arises in one form or another.
There are usually two types of advice given.
1) The tourist applicant must hide the fact that they have a USA boy (girl) friend, or else the application will almost certainly be denied.
2) Best be completely truthful about everything and just simply state the true facts about the USA boy (girl) friend.
Here is a snippet from
http://ukraine.usembassy.gov/business-tourist.htmlB1 or B2 applicants must show that they qualify under provisions of the Immigration and Nationality Act.
The presumption in the law is that every visitor visa applicant is an intending immigrant. Therefore, applicants must overcome this presumptionBelow is a relevant URL and a section from "Ask the Consul" at US Embassy in Kyiv.
http://ukraine.usembassy.gov/ask-the-consul.htmlQ: My girlfriend and I are thinking about getting married, but I want to take her to the U.S. to meet my family before we decide. What kind of visa should she get?
A. You have two very distinct choices: a) she can apply for a tourist visa (B1/B2) or b) she can apply for a fiance visa (K1).
If she applies for a tourist visa (B1/B2), she must qualify on her own merits as a short-term traveler who does not intend to abandon her residence abroad. Depending on the applicant,
the fact that a traveler is in a relationship or engaged to a U.S. citizen may in fact indicate immigrant intent. Applying for a fiance visa (K1) takes longer and is more expensive, but has a greater chance of being issued if and when the relationship is determined to be bona fide.
We review such cases with the understanding that many applicants attempt to use the B1/B2 visa to circumvent the lengthier K1 visa process.So yes by all means, tell the truth if you want to experience visa denial.
But you will feel better for having being honorable.
