Hello,
I am from Bangladesh. As a professional I am a software engineer and working at multinational software company. I have around three years experience in this field. I have completed "Professional Diploma in Software Engineering" from NIIT, which duration was 2 years. I have also completed my Graduation and Masters in Physics.

I have some queries regarding Skilled Independent Visa (Sub-Class 175):

1. 
   Am I eligible for applying PR at this moment ?How many years of experiences are required to be eligible for applying as I have Professional Diploma related to my profession?
