I did the same about 2 weeks after I submitted my application and I got ppr after 4 months. I think that's decent timing. I don't know how travel history affect PR processing but as long as u didn't stay for more than 6 months at a stretch, I think the effect is negligible. Again, I am not sure about this. My travel history is less than 20 in about 6 different countries.
Thank you for reply, but can you please advise if there is a form that I have to fill; if yes, will they send this??
Thanks for helping..
