Guys, I think its great that guys going through the mess with the K1 and K3 are providing help. For the newbies out there, the process will test the bond of the relationship with your lady. It is important that a discussion board such as this be constructive in nature. Too many times we have seen guys putting each other down and moaning about this and that on this site. It is to bad grown man cannot remember what they should have learned in kindergarden.
Anyway, two decent sites are visajourney and the british expats forum. You will read about incredible stories of visa BS.
Be prepared, our government will treat you like trash and your tax dollars do not mean anything to them. The new agency that is protecting us from the bin ladens of the world are also responsible for the visa reviews. It scares me thinking the agency that is protecting the public needs 3 weeks just to tell you they recieved your application.
Just when people thought it could not slow down any further, the K3 approvals have almost come to a halt. It is now taking 14 days to process 2-3 days of applications. They are getting further and further behind. Furthermore, as of April 1st, the Bogota embassy have even managed to make the process longer (K1 or K3).
It I had to do it all over again, I would do a K1 and make sure it is processed in the Vermont office. The employees are on "pay-for-performance" and are known to actually take applications home with them to work on.
For the newbies, you have selected a long hard road, but it will be well worth it with the right lady.
