Well, I did it! I flew to the UK today to take my KOL and passed!
I wasn't exactly sure what to expect from the IO since I was only flying in for the day to take an immigration test. But the IO wasn't concerned at all. When she asked me the length of my stay, I told her I was only there for the afternoon. She then asked why and I explained I was there for the KOL test. She asked if my husband was British, then asked why I would fly over for the test instead of getting the spousal visa first and just take the test once I was settled in the UK. So I explained how this way saved me much more money because I was only applying for one visa, opposed to two, and I'm flying non-rev so I'm not paying much for the flight. She told me it sounded like a good plan to her and stamped me in with a 6 month visa. Incidentally, on the UK landing card, I put down the address for the Kensington Library, where my test was held, for my address while in the UK!
The test itself was an absolute breeze and I finished in three minutes flat. Feeling I may have finished a little too quickly, I rechecked my answers twice and that was still only another five minutes. Once you finished testing, you were asked to wait outside the testing room for your score. I know I got 100% because I studied like a madwoman and know that book forwards and backwards. There was no way I was going to fly all that way to London only to fail the test.
Anyway, I spent the rest of the afternoon hanging out in the lovely Kensington Library browsing through some books, then I did some window shopping on Kensington High Street before making my way to Heathrow for the evening flight back to Philly. I'm back at home now, and although I'm exhausted, I'm way too pumped up to go to sleep so I thought I'd share my experience with you all!
P.S.
It's too weird that it was only yesterday (Thursday), I woke up in my own bed and spent the afternoon doing laundry. Then this morning, I was taking a citizenship test and hanging out in London, and now, hours later, I'm back at my house sitting on my couch. Crazy.
