@SinnamonFairbanks, fat transfer is the way to go. I have seen many Asian ladies that have had the procedure. Almost no detectable scars - incision points heal extremely well. And it is your own fat, so no one can truly say your breasts are fake.
I imagine you would have to go to Japan or South Korea for the an expert procedure. But I am sure you can find something in the US. For this type of procedure, you best not bother with going to any other countries.
I think the only limitation with the procedure is the number of cup sizes you can increase. But if you are going for a truly beautiful body, very large cup sizes are ridiculous in normal society.
Too many long term complications with adding foreign objects into the body. Do your research and wish you best of luck.
