Anyone have a suggestion on best way for my girlfriend to secure a tourist type visa to come to US in July? Ive been living in VN for several months teaching. I'm in my 50s and she's in her 40's. I plan on returning to the US soon and would like my gf to come experience the US for a month. Idea is to see if she/US are comparable. If she likes US our next step would be for her to come back to US on a fiance visa.( this visa dictates we'd need to get married within 90 days of her arrival). So, my idea is for her to "test the water" in the US before doing the fiance visa. So, my question is:
What would strengthen her chance of being able to visit US in July?
July is over 3 months away. Is this enough time to get the visa? I understand she may have to do an interview in Hanoi.
Other advice would be welcome. My gf does have children (14 and 18 Years old) , a mother and a house here in VN.
Thanks in advance
