Because they aren't looking for him? Look, deportation usually happens because they find out about your status after you do something else, in most cases. Let's say he shot someone. Well, then they find out he's illegal, etc. then USCIS is generally alerted and they start deportation proceedings. Deportation isn't where they bang on your door, take you away and put you on the next plane back to your country. It's a lengthy process, just like everything else.
He can pay his taxes because he probably has an ITIN (my tourist visa husband pays his with one), and can hold a job because his employer either never checked for the proper documentation through the I-9 process or if they did, your boyfriend has fake docs. When I give my employer my SSN card, they don't call the social security administration and make sure it's valid and it's really me. (It is me, by the way.)
If he entered legally, you can adjust status just like both john & marlene and I
both said. My husband and I have filed for AOS, as well as many other people on these boards, who adjusted from visas such as student or tourist - people with overstays, with unauthorized work - and it is forgiven through marriage to a USC. There's a lot of paperwork involved, but if he entered with inspection, your chances are pretty good of not having many issues - of course, a consultation with a qualified immigration attorney is always recommended, but you don't have to hire anyone if the case is simple enough. (Though with all the paperwork, even the simple seems complicated which is why a lot of people will recommend at least talking to a lawyer.)
If you don't adjust his status, he is very limited. The goverment may never find out about him, but forget any island vacations unless you only really want to see Hawaii - forget visiting his family in Jamaica, forget any really golden job opportunities - if he has a decent job now, it's likely he got it with the work permit and HR never came after him, but forget moving onto greener pastures.
The longer you wait to fix his paperwork, the harder and more difficult it will be.

What doesn't make sense to me is that he can continue to work, pay taxes, pay a mortgage, pay property tax - just like ANY U.S. Citizen and no one is concerned with him!?!?!
Do you think we should just leave it be and not try and complicate things? I'm afraid if we try to figure out his status or what he should file that will open up his file and he'll be deported??
