Could you please advise on the plan for H1B 2017?

I have a work experience of 1.5 years as of now. I am very new to this forum.

I read through some blogs and realised it has to be planned well in advance.

I want to apply for jobs in US in the same domain. I do not have any offer with me at present.

This may be a good starting point - H1B Application Timeline, Deadlines, Planning - RedBus2US
