I agree with what PopNYChic, has said along with many others, you can find females that will like you for who you are, just like anywhere else, but again these things depend on a lot of different situations.
For one if you are older and looking for someone much younger, guess what normally what your biggest attraction will be is what you can bring to the table to make her life better, if not she normally would be with someone her own age.
If you are just a visitor and not living there, and have roots in the community and the country, again, what can you do for me, because then you will be perceived and probably rightfully so, as some one who is looking for a good time and is not looking for anything committed. So if you find someone that is willing to play that game with you, just as it has to be worth your while it should be worth her while don't you agree?
I mean if you met a woman from wherever you are from, and the same conditions applied, you would expect the same, or are you someone, that expects to get everything you want and don't have to give anything back?
I don't think any of this is unreasonable on the woman's part, especially if there is a great age difference, and in your case that isn't the case as you stated before, but I am trying to make this a general answer, and not specific to you.
The bottom line is expect to treat women the same as you treat them anywhere else, if you do that you should be fine; of course if language and cultural differences also are there you have to work to overcome them as well.
