how do you qualify? just have to be legally able to marry?
the only thing i can think of is maybe financially, i may need a sponsor for the I-134
also how does she proveshe was just here on vacation and found me and we decide to marry?
Just have to be legally able to marry, If just marry and adjust status YOU need to provide an I-864, and if income is low, you may need a Joint-Sponsor.
Prove just here on a vacation, how about a Job, apartment, or home, etc.. back in the home country that they were planing on returning to but now things have changed.
Some of the terminology used to describe what is needed for you to marry and her to stay has been a little misleading.
The issue of intent refers to your fiancee's intent when she entered the US. If she didn't know you before she arrived, or at least you had never met in person, it would have been extremely difficult to enter the US with the intent of marrying you and immigrating.
She MIGHT have to "prove" she didn't have intent but generally what is required is to satisfy an adjudicator, not "prove" anything. Showing some supporting "evidence" is a good way to satisfy the adjudicator.
All this is really moot, if she actually has a need to return to her home country anytime soon. It only works if she can feasibly stay for several months after marriage.
Otherwise, she'll need a visa to return after she leaves. Which of three possible visas would depend on whether you decide to marry before she leaves. Marrying is totally legal regardless. It's how you arrange for her to live here that requires the effort.
