Severence package help

Hello All,

Please can you help me with below issue.

I was working with company A. I transfer my H1 to company B. My H1 got approved with company B on last Friday.

Yesterday my company declared work force reduction. They are offering me severence package which will be paid biweekly after 16th april as it will be my last working day.

Company B joining date is 26th april

Is it ok to accept severence package and signed the release documents.

Or should I decline it and give 2 weeks notice.

Will it affect in future for I140 transfer purpose??

Thanks in Advance
