I have said this before but it seems no one has ever picked up on it. I reversed this meeting and greeting system. I just put up my picture and my profile on several sites so I assume that most who wrote me first were already at least a little interested in me. No scammers. And I took the time to at least reply to all. Not hundreds I assure you 
Overall I wasn't that serious about searching,been around the block and world a few times , there are single people anywhere. I feel if you
are open , active, semi outgoing, and personable you are going to meet people all the time. Traveling anywhere generally enhances that of course, whether traveling to the grocery store or the other side of the world.
I threw up a profile on several websites both locally and internationally
(and some reputable ,and not so reputable)
I did not initiate any letters , I replied to those contacting me.
Sure I had basic criteria in whom I would reply to , but I generally replied to all and just saw where it lead. I already knew most would not be compatible, legitimate, or we simply would not have any spark between us, and that's just in long distance contacts. In person that ratio is similar so its a long shot and should be treated mentally as such.
I felt that sooner or later one would stand out, that I just had to visit
and would act quickly about visiting once I felt that way.
If no one stood out,or contacted me, that was perfectly ok as well.
I think that's a fine method if you are confident in life and relationships,
and don't have any timeline or preset ideas.If using it simply as a means of expanding your local dating or meeting people thru regular life.
It's a poor method if you have any kind of timeline , concerns for meeting someone in any foreseeable future, or relying on it as a sole source to fill a relationship aspect in your life.
If you have made a concious decision to meet a foreign woman , then my advise would be to write /contact as many as you can locally and abroad. I'd advise concentrating locally at first if possible, as even casually dating someone already in your country from that culture will help you learn if its something you should pursue.
