Many people have taken to various forms of social media to share pictures and provide information about themselves. In some cases, its used to communicate directly with another person. Unlike emails and phone calls, a record of your communications are not so easily deleted or managed for privacy. Its important to keep this in mind when you apply for a K1 Fiance Visa or a CR1 Marriage Visa. Your pictures and statements reflect information about who you are and what you are up to.
Imagine filing for a Fiance Visa and stating that you are in love with your fiancé and yet having current pictures of a another boyfriend or girlfriend at home or pictures which strongly suggest a romantic relationship with someone else. Such information will likely be seen by USCIS or the US Embassy and in such a case could seriously compromise your credibility. If USCIS or the US Embassy does not believe you, you will not get your visa.
