[Kasey]

Another question which may help in your decision, like Nungesser said, how many regions (only one or two or twenty?), also do they assign you to a region, do they give you a choice of regions or do you not get assigned any regions unless you request and just go on general waiting list and find out your region at the time of your referral?
Also investigate the regions they work in--things like a very long in country flight to the Far east, may not appeal to you, do they know the time between trips with their regions (although this is variable now with russia), do those regions tend to waive the ten days on the second trip?
Ask what their policy is if you have to turn down your referral while in country on the first trip, will they make you come home and wait or will they work to find you another referral while in country.
Do they only do blind referrals (i.e you either know nothing, or you know basic, age and sex) or do you get referrals with photos and/or video and medical info?
These are just some other things to consider.
Best wishes!!
