The K1 Fiance Visa requires the US Citizen and the foreign fiance seeking to obtain a fiance visa, to have met in person within a two year period immediately preceding the filing of the I-129 Fiance Visa application form. The best evidence of a personal meeting is a time stamped picture of the couple together, preferably in front of a well know landmark in the country your claiming to have met in. I recommend that the picture be taken by a camera that automatically time stamps the picture. In the absence of a time stamped picture, you must write the date of your meeting on the back of the picture.
Other good evidence of a personal meeting would be airline ticket stubs, boarding passes and receipts which include the passengers name, and flight information. A copy of your passport entry stamp would also be good evidence as well. When you enter another country, you will receive an entry stamp bearing the country name and date of entry. Make a copy of this to provide USCIS with your other proof. If you are in the Military, and living in the country where your fiance resides, or where at the time of your personal meeting, a copy of your Military orders or a letter from your commanding offer stating that you were present in a particular location and time of meeting would be good evidence in that case.
Other evidence like, movie, hotel, and restaurant receipts can be helpful as further support, but by themselves will not be sufficient to prove that you met in person.
As with all other types of evidence to meet the other fiance visa requirements, its best to provide USCIS with everything you have. If you have any questions or wish to discuss your Immigration matter, please feel free to call me toll free at 1-888-515-3529.
