WOW.
The "alternate immigration process" often described of entering on one visa, getting married, then filing AOS and staying in-country as "pending AOS" while the I130/AOS is in process probably will not apply to this case. The overstays that are routinely forgiven (without penalty) generally involve filing the AOS WHILE THE VISAHOLDER is in legal status, and the visa usually expires during processing so they can't travel outside the country until processing is complete.
The tough ones, and most risky, are the overstays who marry and file AOS as overstays, but...... with the new "penalty" those are usually forgiven as well. Those are usually people who drive, walk, or swim across, stay, work illegally, meet someone, get married, then when they file there is an additional penalty they have to pay (it's like a thousand bucks or so) and a pretty tough AOS process but usually they get through it. If they travel outside the country during processing, they get nailed with the ban.
The problem with this case is that the visa category type is specifically prohibited from adjusting. The way the regulations are worded, it implies that the person has to return to their home country to wait for I130 processing and have the visa granted there. Chance of waiver on ban is pretty good, if the marriage is legit, but they're separated during processing. Which kind of sux for this couple because there is an anchor baby involved.
Yep, an attorney definitely should look over this one. Kind of a special case.
You're not making any sense.
An overstay by definition is not someone who entered illegally. You can't overstay a legal stay if there was no legal stay to begin with. (I'm not sure how the citizen child of a citizen is an anchor baby, but that's unimportant.) An overstay doesn't need a waiver for EWI.
So let's have some accuracy here.
1) If you entered legally on a visa and overstayed, the overstay will not be a bar to attaining permanent residency through marriage. It doesn't matter how the overstay happened or when people filed for AOS having overstayed. There is no penalty fee for filing AOS from an overstayed visa.
2) If you entered illegally, you will not be able to adjust status even through marriage. You'll have to go home, file for a visa, and then successfully pursue a waiver in order to return. There is an extra fee to process this waiver. There is no penalty fee.
The question here is whether the C/D visa precludes someone who entered on it and overstayed filing for an I-130. Looking at the instructions, it is as fwaguy says: a little ambiguous. Included in the category where it says the person may not adjust status is also, e.g., illegal work, an overstay, , which we all know is not a bar to adjusting status based on marriage. Also included in that category are EWIs, which can't adjust. (The form is right -- you don't file based off of your expired tourist visa, but off of an approved or concurrently filed I-130.)
Verdict: ambiguous.
So the question is whether the crewman is treated more like an EWI or more like an overstayed tourist visa. I suspect, since it is singled out, that it is more like an EWI, but this is a case for an attorney and not speculation. Your friend shouldn't leave until he gets a definitive answer, because this might be the sort of thing resolvable without a separation. Leaving will trigger a ban, and that *will* require a waiver.
