I Was Laid Off By My Employer, But The Expiration Date Of My H-1B Status (As Stated On My I-94 Card) Is Next Year. Am I Still In Valid H-1B Status?

No. Your H-1B status is tied to your employment. Thus, after your employment is terminated, you are no longer in valid H-1B status, even though your I-94 may still be valid until a later date.
