H1B Denial and I-94 Expired

[Ahir]

Hi There,

My H1B extension just got Denial, the day before my I-94 expiry date. 

Here my questions, and looking for some answer:

1. Is there any grace period to stay in the USA?

2. How soon I can file new H1B?

3. Do I and my wife both have to leave the country? 

4. Can I file an MTR from different company and file a new H1B from someone else at the same time?

5. If in case I file a new H1B, and got approved with premium processing without leaving country, can I just go to Canada/Mexico to get stamp?  Or it would be only my home country?

No grace period if the I-94 is expired. You and all dependents have to leave the country.
