Question About filing I-130 I 485 for mother with expiring I94

[sungop]

Hi

My mother I-94 is expiring in a week? Can I file a I-130 & I-485 after it expires?

Should I first extend I-94 with Form I-539? While I-539 is pending then can I file I-130 & i-485?

Thanks

You should file I-130 and I-485 before her I-94 expires.

If that is not possible, you should first file I-539 and then I-130 and I-485.
