I wouldn't go to Michigan for "the best plastic surgeon" state-side... The best I would imagine to be either in Beverly Hills or NYC. Just cause, the demand would be higher in those areas... Plus if you're Asian, I don't think you should trust your face to a white doctor... Also, when it comes to aftercare, I believe locals and foreigners tend to receive similar treatment... But for a foreigner fending for his/herself in a foreign country, mediocre post-op care feels worse than for a local living at home.
Some clinics that cater to foreigners offer special and extra services such as guesthouses, but as Eightbelow says, you shouldn't let that sway your decision.
The place I went to didn't offer a guesthouse, but you could come in and schedule a shampoo and laser deswelling treatment whenever you wanted, a service offered to both locals and foreigners. And many doctors appreciate foreigners' business more because they know that we've traveled far to trust these doctors with our faces/bodies. A respectful doctor would recognize that and feel honored. At least, that's what I was told from my clinic and Londonchick heard something similar from her doctor.
Just pick a kind, patient, and honest doctor, not one that seems frazzled and too busy to answer your questions. I think your consultation can be a good indicator of the type of surgeon a person is...
