Hi Amlan70,
This is just my understanding of some of the things you ask about:
When you apply for a tourist visa, the CO will be interested in evidence that indicates you will be returning to India, and not staying in the US permanently. Proof of strong ties to your country, in addition to your letter of invitation, will help... I suggest you read this:
http://www.travel.state.gov/visa/frvi/deni...nials_1361.htmlIt's not that DOS doesn't issue tourist visas to people your age, just that they are less likely to issue tourist visas to people from "high-fraud" countries (I believe India would qualify) who do not have strong ties to that country. Younger people tend not to be quite so "tied" as older people, and young, unmarried men tend to be, some might say, even less "tied" to anywhere in general.
I see you have gotten some good suggestions in the K-1 forum. I agree with those posters that you may have better luck with your USC fiancee visiting you. And if I were you, I'd meet first and if you still feel the same about this woman, go for the K-1. Having done some considerable dating via internet in my single years, my experience was that I could get very enthusiastic about a certain individual, only to find when we met that there was no "chemistry" as they say. I hope she is everything you hope she will be.
And as to the age difference. When you get to the stage of Consular interview (you will be interviewed at the US Consulate that serves your area), they will be interested in determining whether or not you have become engaged to this woman for the purposes of immigrating to the US. If your relationship is not within the cultural norms of your society, this can raise a red flag for the Consular Officer.
I have limited knowledge of Indian customs, but I know in Nepal, it would be very unusual for a Hindu man to marry an older woman/divorced woman/woman with children from a previous marriage. I'm not assuming you are Hindu, or assuming anything (I hope), but I suggest you look at your relationship through the eyes of the CO. And if you think you have an obstacle there, do what you can to overcome it with evidence that your relationship is real. As someone else said in another of your threads, multiple visits is very good evidence. It should be noted, however, that multiple visits by the USC only really indicates the USC's intent (ie, not being paid to marry someone so they can immigrate and get a greencard). And I've also read from more than one source that hand-written cards are better evidence than emails because they show effort, which is something "sham" arrangements apparently lack.
Well, I hope this post isn't discouraging. You can definitely do what you are setting out to do, and I hope everything turns out just how you'd like it to. But move forward with your eyes open, and accumulate as much evidence as you can.
Whoever flies to meet whomever, be sure you save all your boarding passes! And take lots of photos on different days, with different people, in different places, wearing different clothes.
Well, that's longer than I intended! Sorry to be so wordy. Best wishes,
Maya
