Jennifer ,
I'm from india .I don't know much about overseas
market.But i can suggest a few things.
It's better u learn something more than core java.SCJP will give u an advantage only u are qualified in other areas also.
Probably u can choose JSP and XML.Offcourse JDBC is a must for all java developers.
