what is receipt number and petition tracking number ?

Hi All,

I have a doubt on my consultant, whether they have applied for H1B regular or not?.. How would I come to know my petition status? can any one help me by answering.

  1. what is receipt number? whether we get this number once our application picked in lottery only?

  2. Still how many days we need to wait, to know about our application status whether it is picked or not?

  3. My consultant telling it will take time upto may 20 to know about the status on lottery? Can I believe them?

Can any one help me please.
