I clicked the "some foresight" option. That being said, most of the foresight was just making sure my now hubby was the one. I'd been married once before and didn't want to make another mistake. But I was pretty sure, pretty quickly. The rest of the foresight was just in researching the visa situation--pretty much knew it'd be fiancee, then FLR, then ILR, then citizenship.
I was recently divorced and staying at a friends (no real lease), also had some money saved to cushion me and fund the move. I got rid of most everything I owned (after the divorce I had already downsized, so it was just downsizing a bit more). I would not have been able to justify the cost of shipping stuff over. Mostly I gave stuff to friends, donated my books to used book shops, art supplies went to the poor students I worked with, my sister got my grandmother's chest, and my old work got my futon to use as a couch in the breakroom. I owned no other furniture. I had great fun giving my stuff away!
So basically my move happened in two stages. The first stage was coming over for a 6 months visit. This is when my now hubby proposed to me (I pretty much knew he was going to). I had brought over my smaller harp and my big backpack. My fiddle was already in the UK from a previous visit (I left it there, knowing I was returning very soon, and borrowed a fiddle from my teacher when I got back to the US)
The second stage was packing up 6 *small* boxes of books, CD's and some art supplies and mailing them to my hubby-to-be in the UK. I brought my bigger harp (the case was stuffed with clothes to protect it and the harp in it's case was bubble-wrapped and put into a big box. It went on the plane as extra baggage, costing me a mere $80 as opposed to upwards of $1300 to ship it), and two suitcases, plus my laptop as my carry-on.
That's it. I left about 5 boxes of stuff at my friends' house in the US and I don't even know anymore what's in them, so obviously I won't ever need that stuff!
