Prove to me that you actually love each other

Some of my friends maried foreigners and moved to their countries years ago. This was one of rare possibilities of how to move to another country legally, how to cross the iron curtain with the chance of coming back whenever you wanted to. Tens and tens girls I used to know as a teenager took a chance and live more or less happily around the globe. As far as I know none of them had any trouble with their immigration in those days. They just got their second citizenship and enjoyed their new passports allowing them to travel without asking the Czech authority for any permission.
There also were and are foreigners who maried Czech girls as Czech girls (I don't mean those fashion stars like Kurkova or Nemcova but those girls next door) are one of the prettiest girls ever. These guys decided to stay with their pretty wives in my country and as far as can remember they also didn't have any difficulties in getting their immigration permissions, even in those days of deep communist totalitarianism. The regime was tough but tried to look friendly in some cases.
There was some US or perhaps French movie about a freshly married couple - one of them was a foreigner - facing many so called funny issues with US immigration authority. The movie wasn't too clever, trying to be bittersweet but was more bitter then sweet actually. But still it was just a movie. In other words, I was under the impression this was only a movie. Oh, I terribly misunderstood it. The body of that story was real.
Imagine a man from the UK who maried a women from the USA. Imagine they've had to wait for their “blessing” given by the US immigration authority for five years. To become a permanent resident of the United States they had to answer questions like: “Prove to me that you actually love each other and that this isn’t a marriage of convenience.”
The man who had to face this life trial by fire lay a question for all his blog readers: „Look at your husband, wife or your boyfriend or girlfriend. Imagine it being in someone else’s power whether you get to stay with them or not. Now you have a basic understanding of the pressure we’ve been under for the past 5 years.“
I wouldn't be surprised if this happened to a man from Irak or Afghanistan or from some poor African country, or perhaps from Mexico or Venezuela or so, but he came from the UK. From the country that is claimed to be to most faithful ally. Just go and read the last entry of a blog whose secondary title sounds „Because some things just don't make sense“.
Incidentally, it was almost impossible for us to cross the border to the West but it was also hard to get to the former Soviet Union even though we were a very faithful ally. We had to ask for visa to get to Moscow. However, there are not any similarities between then and now, are they?
