The time it takes in your situation to obtain a K3 visa varies depending on the country in which your fiancee resides and where your marriage took place. Timing changes constantly, but in general is measured in months. Note that the time to process a K3 Visa for marriages is different than Fiancee K1 Visa timelines.

Other factors to consider for either a K3 visa or a K1 visa will be whether the case is prepared and presented properly, how quickly problems can be identified as they arise and how quickly they can be solved. Issues in timing often arise because the USCIS and the overseas U.S. Consulates combined are perhaps the largest of the government bureaucracies, apart from the U.S. military. Unforeseen problems during processing can be difficult to identify, difficult to locate within the bureaucracies, and then difficult to resolve. Unfortunately, once an unfavorable decision is made by an immigration official it can be nearly impossible to get him or her to change that opinion. It is therefore important that you present your case correctly from the start and check the case at each stage of processing.

You should consult with experienced immigration attorneys who specializes in K visa immigration to learn more about timing issues for your situation.
