petition aprvd.no client letter r inhouse project.yet to go for stamping.

Hi
I got my petition approved without client letter or in-house project details in petition, saying client will give letter only if i’m in US and also close to work commencement date. but now that client is not available. am looking for alternate client as there’s no inhouse project. what should i do now?
1.appear for stamping without client letter, saying that client wants me in US to attend interview and offer job?
2.search for different client if possible and file new LCA and amendment to the petition, get client letter and go for stamping?
this is a new job and am in India. please suggest.

Thanks

1.appear for stamping without client letter, saying that client wants me in US to attend interview and offer job?

This will be for sure rejection. Do not go this way.

2.search for different client if possible and file new LCA and amendment to the petition, get client letter and go for stamping?

This is correct way
