US Immigration from Philippines

My Fiance just got here a week ago and we are trying to figure out what to do, We saw that we need to file an I-485 Adjustment of Status after we got married but my question is do we REALLY need to file I-765 and I-131? I was under the impression that once AOS is approved then he can actually work in the USA legally and can travel out of the USA once that AOS is approved? Am i correct? I understand that filing I-765 will make it quicker for him to work legally while waiting for the AOS result....

Thank You in Advance for any answers.

My fianc e and her two kids were just granted k1/K2 visas and will be here in two weeks. We plan on getting married in March.

For insurance purposes, they need to have SSNs or be in the process of getting them. I understand that my fianc e can get one as soon as she gets here. But the two children will have to apply for EAD. Which is $410 each.

I also understand that you can apply for EAD along with AOS and there is no additional fee for the I-765.

What have others done so as their families are covered by insurance and able to get SSNs so they can be claimed on taxes?

Hello, beautiful people.

I submitted my AOS packet last week and I just realized now that I failed to submit the 2nd page of DS-3025. Would that be an issue or reason for RFE?

The first page of my DS-3025 was marked completed and I also submitted a copy of my covid19 vaccination along with my other vaccination records.

Do I have to file the K1 and K2 applications together, or can I file the K1 first and the K2 later when I get my bonus?

I'm sure this question has been asked before. I have not had any sucess saving the form mid way and coming back later to complete it. I get a blank form and have to start over again. Is there a way to save it like a normal pdf?

Thanks
