I don鈥檛 think that i鈥檇 Go through the hassle of obtaining a 鈥渇raudulent K1鈥 in order to get your girl to the US for a few months of vacation.
Have you ever met her and spent time with her in person? That is a requirement.
Further:
You must intend to marry each other. You must be able to show USCIS that you and your fianc茅 intend to marry each other.聽 If this is not your intent then this is not the right type of non-immigrant visa to use.聽 USCIS will require both you and your fiance to sign affidavits under oath.聽 These affidavits will state that you intend to marry each other within 90 days of your fianc茅 entering the United States.聽 In addition, you will also be explaining聽 how you met each other and how your relationship has developed over the time you have known each other.
You will also need to prove that you have a bona fide fianc茅 relationship with each other.聽 (This is generally shown through email correspondence, evidence of gifts, receipts and photos of the engagement ring(s), evidence of trips you have taken together, affidavits from family members and friends etc.
In addition, you can help prove the bona fides of your relationship by showing聽 Facebook posts from friends and family congratulating you on your engagement. (Yes, USCIS does know how to use Facebook and they do use it, and other social media sites and other sites (think Google, Twitter, LinkedIn etc.) at times, when investigating cases.)聽 Therefore, as an aside, be very careful about what you post on Facebook and other social media sites.聽 USCIS can use these sites to help make a determination in your case (without you being aware that they are doing this).聽 USCIS believes that these sites give it an excellent vantage point to observe your marital relationship.
You must also show USCIS that you are treating your engagement like a typical engagement in your fianc茅e鈥檚 home country.聽 If, for example, in your fianc茅e鈥檚 home country it is typical to have a formal engagement party then you should have one.聽 You need to make sure you comply with the cultural customs of your fianc茅e鈥檚 home country.聽 If this is not done then your case can be denied at the fianc茅 visa interview level.
As to your future K1 opportunities:
You must not have filed more than two fianc茅e visas in the past nor had an approved fianc茅e petition in the last two years.聽 聽Once again, a waiver is available but there is no guarantee that it will be granted.
USCIS will notify the person receiving the fianc茅 visa if the U.S. Citizen fianc茅 has had 2 previous fianc茅 visas or marriage visas approved in the past 10 years.聽 If this is your case then you should notify your fianc茅 of your prior petitions.聽 She needs to be completely aware of your past attempts to bring other fianc茅s or spouses into the United States.聽 If she is not aware of these past petitions and learns of them at the interview the case can be denied.
I think that I would play this correctly in trying to get her there. In my case, I can鈥檛 bring my GF over either as she doesn鈥檛 meet the stringent requirements of the US for a tourist Visa. It is what is so, I hang over here with her.
