Since it's after 1AM I'm gonna post this and hope it's not removed...
I do not know if David and Linda are infact still together or not, but there is a big chance that they are not. For those who are not familiar with how "US/the rest of the world" relationships work in real life (i.e. not in a FOX fairy tale) let me give you some interesting insight :
--- Every time Linda wants to come to the US to see David she needs to get a visitor visa, since Chech Rep. is not in the visa waiver program.
--- Assuming she has a bf (fiance?) in the US, there is a BIG chance she will not even get the visa. Or she can be refused entry to the US by an immigration officer at the border, because they are very careful in letting people in who might have the intent to immigrate (i.e. marry).
--- If she is indeed allowed to enter the country, she will only be allowed to stay for 3 months at a time, and then every time go through the same process again (becoming more and more suspicious in the eyes of the US immigration due to the more frequent visits).
--- If at some point they decide they want to get married they cannot marry on a visitor visa because it would be regarded as visa fraud. Anybody who enters the US with the intent of getting married without the appropriate immigrant visa in hand is in big trouble with the INS (i.e. deportation trouble).
--- The only way they could do it would be:
1. option: David petitions for Linda's fiancee visa, which takes from 6 to 8 months to process through the Texas service center. Linda then needs to get a full medical exam, an interview at the embassy and has to submit her police records and a bunch of other docs. Hopefully she never got in trouble for smoking pot in highschool! After that she goes to the US and has 3 months time to marry David. If they do not marry she is required to return to her country.
2. option: They get married abroad or in the US, but Linda HAS to return to her home country, so that David can petition for her spousal visa, which takes anywhere from 6 months to 2 years to process. Similar to the previous procedure...... She then moves to the US after receiving the visa.
--- This relationship will cost them A LOT of money: plane tickets (about $1000 for a round trip), phone bills... visas $50 to $200 each, the whole immigration process estimated to $1000 and over in forms only, plus an immigration attorney (more $$$).
--- To be able to EVEN GET a fiancee/spousal visa, and later on apply for her legal status in the US, David has to meet certain income requirements to sponsor his fiancee/wife. Hopefully he makes enough money as a cowboy???
--- After Linda moves to the US and they are married it will take months for her to receive Employment authorization and Advance parole that will enable her to travel outside of the US. It will take about 2 years before she receives her conditional green card, and 2 more years for her to receive her 10 year green card. It will take 5+ years before she can apply for citizenship and 2+ years before the application is processed.
That is just a very short version of how things work of course, assuming that everything goes perfectly smooth (hahaha, yeah right!)... Sounds like fun, huh?
... Least but not last, after a couple of months of honeymoon their marriage will be under great pressure due to her dealing with culture shock and not being able to fulfill her individual goals, as she will sacrifice her interesting life as a model to be a cowboy's wife. David seems to be very conservative, so her unsatisfaction will grow, due to the fact that her life will become limited to cleaning, cooking, taking care of her husband and watching reality TV.
