Query regarding residential status and itr form.

Hi All,

I'm an IT professional(work for Indian IT company).

I had travelled outside India on deputation (onsite) in Nov 2017 and returned to India in 2nd week of Oct 2018.

I have below queries regarding ITR e-filing for FY 2018-19:

1. What will be my residential status? As per my understanding, it should be non-resident.

2. Which ITR form do I need to fill?

3. Do I need to declare the salary that I received while being outside India?

I'm very confused about the 2nd question above as I have got mixed results on the research(talking to people/company's accounting group,read online articles, etc) that I have done so far. I think that I need to fill ITR form 2.

Please advise. Thanks in advance!
