What is the timeline if DACA marries someone with a Greencard?

Just curious what that path would look like in terms of timeline.
Marrying someone with a greencard vs. marriage (obviously, easier path)

You'd need an I-601A waiver unless you've got 245(i) or got DACA before turning 18 and 180 days old.

Alternatively if you entered with inspection you could wait for them to naturalize and then adjust.

Timeline, I'd expect like 2-3 years if you need a waiver.

So let's say, entered with inspection.
Also, my main question is: While things are being filed, during this interim process (while the very first paperwork goes into process), are there any privileges regarding travel outside the country? Or... do you have to wait until you are fully a GC holder to be able to travel?

Bit of a nonsense question. You won't be able to adjust until the GC holder spouse naturalizes, and before when you file for AOS and get approved for advance parole you can't travel.

I-601A might be faster depending on how long it'll take for the GC holder spouse to naturalize.

So basically, marrying a green card holder (let's say if he recently received it less than a year ago), the path to traveling abroad would be MANY years. Right?
