As his plan is to stay for longer time period so can he carry 2000$ cash+6000$ in forex card along with his updated bank statements??
2) another question is that if he carry 8000$ in total+his updated bank statements..does the amount of his bank statements are also included in 10,000$ limit that one have to declare?
Yes, he can carry as much or as little as he likes.
As @k.h.p. said, bank statements are not included in the $10,000
