Is it possible for DIAC to make any rule changes overnight (without prior notice). I got an EOI and am planning to take some time before lodging (while I arrange the money). And I was worried what if DIAC changes the rules before I can lodge. The rules which would affect me would be if DIAC made at least a year of experience in the selected occupation compulsory (I have the points without work experience), or if DIAC made it compulsory that after grant of visa the person has to work in the selected occupation only. Should I worry and lodge the visa as fast as possible or can I take it easy?
