They should file ASAP.

SSN is not required for health insurance -- https://www.healthcare.gov/help/do-i-need-to-enter-my-social-security-number-ssn/ & https://www.irs.gov/affordable-care-act/questions-and-answers-about-reporting-social-security-numbers-to-your-health-insurance-company
 
As for immigration status, even non-LPRs who are not married to USCs and not I-485 applicants may qualify for insurance -- https://www.healthcare.gov/immigrants/immigration-status/
 

They will be out of status and at risk of deportation. It is not  worth the risk, file AOS before the 90 days.

Thank you all for the quick response. I really appreciate this group! Be safe all!

No.  Not for immediate relatives of UC citizens.  Sorry.

Your mom can file an I-130 as soon as she's in US. Since you said that your sister is a minor, as long as the I-130 is filed while the sister is under 21, she'll be placed into F2A which is "current" on the visa bulletin.
 
So your sister will have to wait a bit to immigrate, but just the processing time, rather than the 12-15 years that Crazy Cat mentioned. If your sister is a complete minor your mom can just come to US, file the I-130, file I-131 for a re-entry permit, do biometrics, and head back, she'll have 2 years to return.

As advised, you'll petition your mom, and optimistically she should be in 2 years.
When mom arrives in the US as LPR, she'll petition her daughter (your sister) right away and that should take about two years. If mom doesn't want to leave daughter behind for too long, she can apply for reentry permit after she becomes a LPR. With the reentry permit she can go back to the Phillipines to be with daughter until daughters petition is approved, and then they both can enter the US together.

After your mother's IR-5 visa is issued your mother could do the following:
Enter the US with the IR-5 visa File the I-130 petition for F2A process. I recommend online filing for that: https://www.uscis.gov/i-130 File I-131 application (by mail) to request Reentry permit Open bank account, etc. to establish her US domicile Wait for and then attend the biometrics appointment for the Reentry permit process. Leave the US after attending the biometrics appointment. https://www.uscis.gov/sites/default/files/document/guides/B5en.pdf "you do not have to be in the United States for USCIS to approve your Form I-131 and issue a reentry permit to you if your biometrics (photo, fingerprints) have been obtained. You can indicate on your Form I-131 that you want USCIS to send your reentry permit to a U.S. Embassy, consulate or a DHS office overseas, so you can pick it up from one of those facilities." On the I-131 application the LPR can indicate that the Reentry permit will be picked up at the preferred US consulate/embassy.

If they are married, your parents cannot sponsor them while they are green card holders. They will have to become citizens first. It takes 5 years (possibly longer depending on processing times) to become citizens, and then the category for married children of USCs from Philippines currently has a wait time exactly the same as a sibling visa, nearly 20 years. So in this particular instance it would be faster for you to file a sibling visa.

pls Update.. file sent on 03/26/13, recieved by CSC 03/28/13 and NOA1 DATED 03/28/13 now, waiting for my biometrics appointment.
