H1B from non-profit (approved I-140) to for-profit. Start date only Oct?

[Nissim40]

Hi,

I have an approved I-140 with a non-profit H1B. Planning to transition into for-profit H1B aiming to start this April. If the new employer files H1B with a start date of Oct, can I start working immediately after filling H1B in April?

Please let me know.

Thanks!

If their start date is in Oct, you cannot start working for them until Oct.

If you mean your present H1 is not cap subject and you want to change to a cap subject H1, you can only start in October.
