It would be great to see it as it really is, not just some 'goopy eyed' star struck by love person packing a few things and hopping on a plane, but all that goes with it. There are so many decisions to make for both parties, visa hurdles to go through, being away from family and friends, making new friends, finding a job, settling into life in your new country, etc. It is about so much more than just being in love or being another number on the list of immigrants in the country.
Perhaps not do it as only people getting ready to make the move, but people who have been here 1, 5, 10, 20 or more years to see how they have gotten on over time.
It will be interesting to see.
