Clarification request on K3 Spuse Visa application

[pushbrk 12,822]

No minimum age for petitioner on the I-130 for spouse. However, must be 18 to file I-864.

That's definitive enough for me. What it boils down to is the CR1 visa is out of the question. They'll need to take the K3 route and wait until the USC petitioner is 18 to file to adjust status.

But what makes you sure the I-134 doesn't also have the same restriction? In my quick search, I wasn't able to find definitive info either way, but there's a general rule in US law that someone under 18 usually can't sign a financial contract. That's probably why the I-864 has the restriction, and it might be that the I-134 is similar.

Any idea whether I-134/I-864 could be provided by my spouse's mother, as the one who would, in reality, be supporting us until I gained EAD and got a job?

When the I-134 is used with a co-sponsor, both petitioner and co-sponsor provide an I-134. See my earlier post indicating the I-134 is not actually required and isn't a binding contract. You've got plenty of time to study and decide how to meet the public charge concerns as they are dealt with at the consulate months after the marriage and petition filing.
