When i will get confirmation my Visa is filed or not?

My firm has taken all necessary docs from me for H1B filing in month of January 2013 only; now from 1st April this Processing started; when i will come to know whether my docs are filed or not ? when i will get receipt number ?

Even, I have the same concern. My employer has also filed the documents, but when can I expect a receipt number?

We will know if its a lottery or not by April 5 or 8.

Within a month, we can expect to get the receipt number

same here, no receipt # …
