Hm, after reading over the whole thread, I'd have to say yes, but with some caveats.
To be more clear, I think that it should be up to the government to mandate what the requirements are to receive benefits, as well as to move into the country and become a citizen, and they should be up front about what is required in order to receive what. So in this case, since he moved to the country successfully and was not required to learn the language, and I am assuming was paying taxes and such like any other citizen, I don't think that they should be able to suddenly rip the welfare rug from right out under him, even if he refuses to learn the language. However, I think that if the government had decided before hand that knowledge of the language/agreeing to learn the language was a necessity to receiving benefits, or immigrating into the country in general, then I see no problem with them removing benefits if he had not held up his end of the bargain, or worse, being deported if the later consequence was the case.
As for the whole "cultural assimilation" thing, I think that's a bit too far-fetched to really expect anyone to change their personal culture solely to fit in with where they live. I think that if they wanted to attempt something like this, it would have to be more centered around specific rules that immigrants must follow until they become fully-fledged citizens, such as practicing a standard amount of pre-dictated etiquette as is deemed necessary by the government, and being required to learn the language to a functional level. While this could be very imposing on them, I do think that considering that the country has no obligation to them whatsoever, and is allowing them to immigrate solely for the immigrant's benefit, that they should be able to exercise this level of control over people that they allow into their country until they become proper citizens, or really whatever rules they wish to enforce, since it's their country after all.
I'd also like to point out on the side how silly I think the If you want to keep all your old customs, then just go back to your old country argument is. I mean, there could be a war going on, or the place you are living in could be extremely dangerous and uninhabitable, necessitating a change of environment in order to continue living. While I don't particularly look highly upon the people that move move to a new country, and then constantly flip them the bird, I certainly don't think that there's no reason why they moved here. They moved to wherever they moved for better opportunity/safety, and no amount of cultural nationalism changes that, and if they have been accepted into the country as citizens, then they should be allowed to do as they please, just like the rest of us.
