Need to Change Project before appearing for H1 stamping

[hps756]

Hi,

I have appeared for H1 stamping about 6 months back but consulate have issues me pink slip regarding providing the project details but that time project was really urgent, so i missed that project and unable to provide the documents.
But now company has provided me another project to work upon so i again want to appear for interview for different project and with complete project details.

Kindly suggest me, How can I proceed further as i don't want to lose this chance.

Eagerly waiting for your valuable inputs.

Thanks,

Harinder
