1. When talking to a US startup or US company, how do you ease in and tell the recruiter or the HR about the H1B1 which is easy and totally different from the onerous H1B?

Because most of them have never heard of the H1B1 and many of them get scared when they hear H1B1 because they mistakenly think it is H1B.

2. How cheap and quick is it to get a new H1B1? In dollars and in days.

You are overseas right now and not in the US.

3. What signs can you use to predict which YC companies can support visa?

By their employee count, funding amount, founder origin?
