Im Kaspersky System Admin and Linux System Admin 1&2 and MCITP certified what is the next traninng or courses which i have to take it??

Try to get certificate like RHCE or move on to VMware technology certificate

you can to start take RHCE or MCSE

Which statement about change requests is not true?

Go for Vmware Esxi5.1 and if you are interested in studying more then go for some course in Storage like SAN.
Linux+Vmware+Storage is best combination.

what is Linux System Admin1&2 certified? Makes no sense to me, but I would highly encourage you to take a Red Hat System Admin certification; that would pretty appeal to all Linux hirers but I would also suggest you to take a UNIX exam; like IBM's Certified Operator - AIX6.1 Basic Operations.
Personally of all the UNIX systems I have come across I love AIX the best, its so damn easy to use and I can't recommend it enough
