Arriving in the US Port of entry

Arriving in the US Port of entry
The K1 Fiance Visa is a single use visa, that means that you can only use it once and so you had better make the most of it!  Arriving in the US with all my possessions in two suitcases, my passport with visa paper in it, and my sealed envelope with whatever documents the US embassy had decided to put in inside there, I was keen for everything to run smoothly.  After arriving in the US port of entry I followed the crowd as normal to the US customs desks.  Unlike previous visits to the US, when I was a temporary visitor arriving on a visa waiver and it was clear what my status was, this time I was unsure as to which queue that I should stand in as I was neither a tourist, or an American passport holder.  When I asked a kindly US Immigration Officer about it and explained that I was a US immigrant on a K1 Fiance Visa, she started a new queue and put me at the front(!)
I was nervous when a finally got to see a US Immigration Officer at the US customs desk - there was nothing amiss, I was just anxious that having gone through all the trouble of getting my K1 Fiance Visa from the USCIS, nothing should go wrong at the last minute.  As it was busy (I arrived at Orlando, Florida) and the US Immigration officer has to process all of the documents inside the sealed envelope, which takes some time, he directed me through to the waiting area, where I sat around for maybe fifteen minutes before I was called back to the US customs desk.  It took another ten or fifteen minutes to process the contents of my sealed envelope and take my fingerprints etc.  The contents of the sealed envelope appeared to be mainly just the original application documents and evidence from the K1 Fiance Visa process, but I could be wrong.
Eventually it was over and the immigration officials wished me well.  I still had to collect my baggage and go through more security, but I was through the US immigration part.  From now on, I would be living in the USA.
