1.What is the procedure at SFO?
Ans: Go to this site and download the miscellaneous form for PCC application, send the cashier check and apply for the PCC.

Since your passport was issued in usa, you will get pcc in 1 day plus mailing time.
2.If I obtain the PCC from SFO today, how long will it be valid for
the purposes of CP?
answer: Indian pcc's are valid for 6 months. that means your pcc should not be older than 6 months on the date of your cp interview.

Answer: Tell the doctor you are there for immigration checkup and they know the rest. BASically a full physical checkup but here is a sample:

4. he has been smoking 4-5 cigarettes a day for the past about
10 years but does not take alcohol or any drugs. would this smoking be a problem for his medical exam?
Answer: Generally not. What doctors are most concerned about are contagious diseses that can be spread easily resulting into epidemic. Since smoking is injurious to ones own health and not to others it shoudl not be a problem.
5. would the doctor ask him if he smokes or not?
answer: i am sure doctor would recomend but will not affect immig visa. And I also strongly recommend not for immigration purposes but for your own health. Smoking is not a reason for rejection. So dont worry about it.
6. would the doctor perform some additional tests because he
smokes?
Asnwer: Generally No unless he feels it is good for your health.
5. would it be better if he gets some tests or scans,etc done here
in the US itself before he has his actual medicals in India?
Answer: If you want you can do for your own sake but those tests will not hold good for immigration purposes in india/ any other country where the consulate interview will happen. I am doing a full physical check up next week but for my own sake and since i am used to doing it once a year.
Hopefully i have answered all the questions!
