new application for H1B, also applying to other companies

[alpha_4546]

Hii

I joined a company, in a field that I didnt want to work in long term. This is because my ideal job is much harder to get into. My company is applying for H1B for me. But I am thinking I should start applying to jobs which are closer to my dream job.

1. Can I change jobs while my petition is pending?

2. Can I change jobs after my petition is approved?

3. what extra steps do I need to take for either of the above.

I know there are many knowledgeable members here, so I would appreciate any insight.

Thanks

paul
