H1B visa plan


I have 5+ years of experience in middleware technology and working with MNC company in India.

Want to apply for H1B visa for 2016.

I have lot of questions like :

I will search Visa sponsor and submit it, if my luck favours, my petition will be picked out in lottery.

After my visa interview, i will be having my valid H1B visa. Then i will search from India for US client who offers a job for me.

Then i will change my visa transfer to new client, At the end i will fly to US.

Is there any obligations, or I am going in completely wrong, let me know.

Is there any norm that i should work for first visa sponsor atleast for sometime ?

Thanks in advance.
