anyone to answer and guide me plzz:)

hello......

i am aged 26 from India,completed my bachelors degree in commerce(Hons) in the year 1999 , i have joined a firm as an accountant trainee in the year 2001 and left the job as a senior accountant in the year 2004 ( Experience = 3.4 years).

My IELTS score is 6.5(vocational eng).

i then realized that my future would be much better if i can get a masters degree in accounting and fortunately, i am now proceeding to adelaide in south australia.

i am intrested in applying for SKILLED MIGRATION apparently after i read articles about the demand and good prospects for accountants in australia , but i am now confused whether to apply for onshore or offshore visa?? which one would be the quickest???

another doubt in me is whether to apply for a skilled independent or a STNI (south australia, apparently this one just takes 15 days for assesment??)

Thank u in advance ,

Looking forward for an early replies

cheers!!!!
