i went to Patna, Bihar as part of Unite for Sight.
overall, the raising money part was kind of annoying, but it was pretty do-able. My parents ended up paying $400 because raising $1,000+ on my own was just plain impossible, especially since I am a full time student.
Anyways, if you do choose to go on a UFS trip, let me put in my 2 cents:
The experiences are HIGHLY variable according to WHERE you go. Also, know that Jennifer Staple has never been to ANY of these sights, so volunteers are the only ones that have the "true experience" of what it's like to go on those trips. That said, most of these volunteers are in undergrad and have to suck up to everyone around them/say only positive things so that they can publish, get posted, maybe even get a rec letter out of it, and ultimately get into medical school.
I went as a medical student So i had nothing to lose, and all experiences to gain. My friends, also medical students, went to other places (they went for 1+ month, i only went for a week).
The Patna trip was NOT A GOOD EXPERIENCE AND I DO NOT RECOMMEND IT TO ANYONE. Please go to Either Chennai which has one of the BIGGEST CENTERS IN INDIA AND IN THE WORLD or to Africa where you will get a bigger and more appreciated experience. I am Indian and even in Bihar language was a barrier. In addition, Bihar is one of the poorest states in India, which means that electricity and water would just randomly shut down the second we stepped home from clinic (10pm). The website boasts that "bihar is poor and in need of medical care more than other areas of india" which is absolute nonsense. All of India is poor. THat's like saying Louisiana is poor because they have the lowest literacy rates as a whole, when there are parts of New York City (Chennai or Mumbai) that are EVEN POORER (think beggars that just want to eat poor) and equally in need of care. Bihar is rural farmland so their "poverty" is a per-capta kind of poverty, overall the people are happy and fed. Also, unless you are white, the doctor's house you stay at is pretty douchy and also somewhat of a cheat. He overpriced everything, including the $40 stay. There are 5 star luxury hotels in Bihar that cost $20 a night, and they actually do have 24/7 running water, electricity, delicious food, and electricity! Also, the food was pretty bad because you will eat with the grandparents everyday who essentially never have an appetite. I had to ask the maid to make some ramen noodles (cost 2 cents per packet!!) because we were starving. IF YOU GO TO BIHAR, YOU WILL STARVE. you will also feel unsafe if you are not indian. But I dressed so incredibly poorly I was seen as a local and thus felt safe.
Anyways, there are much better programs out there for medical volunteering that 1) don't make you raise a ridiculous amount of money 2) are more organized 3) let you work with top physicians from US MEDICAL SCHOOLS (not foreign medical doctors that can write you a worthless letter of rec).
hope that helps!
