Travelling to the capital city from within your home country is 100 times easier than crossing borders of other closed countries just to catch an international flight which we had gone through.
In your place, I would not worry even a bit about cancellations or staying any longer, because yours is only 8 months. You still have 3 more months after which you can start worrying :). Good luck with your next flight. Hope your flight won't get cancelled and you will enter the US with no issues.    

Well, she may be forced to choose which is more important to her at some point. I’d strongly suggest you treat your own green card with more respect than she’s treated hers.
 
You should be able to get back well before a year is up, I’m sure you’ll be fine.

Just get back before a year.  Many LPRs have been stuck.  The good news is that once you can get a flight you will be able to enter.

I don't think you should be worried. Because green card holders shouldn't be out US for more than a year, 6 months  is still okay. The only time you should be worried is when you fill for citizenship. They will ask you if you have stayed outside the US for more than 6 months within the last one year. 

Hello all. New member here. Would like to ask for advice about my situation. Im a green card holder and currently Im in the Philippines now. My planned trip back to the states was on March 26 of this year but it was cancelled due to the virus problem. I will be reaching my 6 month stay here on the 22nd of April. Still there are news about extending the lockdown in our city which means no internarional flight. Will I still be allowed to enter the the states if I stay here for more than 6 months? Also my son will be coming with me, its his first time to go to the states with an immigrant visa that expires on April 24,2020. Thanka all.

Also, you can register with the embassy in your country and they will send you email updates. I am in Argentina and registered with the US Embassy in Buenos Aires. I get email updates almost daily from them. I started receiving these emails when I registered with STEP (Smart Traveler Enrollment Program). https://step.state.gov/
 
As someone else noted, KEEP EVERYTHING. Keep all documentation of your intent to leave. Also keep documentation of the dates and measures of the quarantine where you are so there is no question that you tried and could not leave. 
 
Good luck!! And stay healthy! (Because your health unfortunately will also be a factor in returning! You don't want to have a fever when you go to board that flight and then they don't let you on....)

Thanks Mike. Your answer to my question makes sense. My green card expires in 2026. It will be my 6th month here in the Philippines on the 24th of April. 

What is likely to happen is a secondary Inspection. Now apparently some people don’t think that is problem and some people do think it is problem. I am in the latter group.  But this is surmountable. 
 
What can happen in secondary is that CBP makes an investigation as to whether the LPR abandoned permanent residency or not.  It is always a good idea to have a solid story and evidence of intent to maintain residency. Tax returns, rfidrncr if rent or mortgage being paid, current USA drivers license, etc.   

To answe your question yes you will be allowed to enter the USA but not necessarily without consequences. If you return after a 6 month absence you will likely be sent to secondary inspection. You will then be motivated to satisfy CBP that you did not intent to abandon your residency.  As others have said, documentary proof of the original travel date, and of your lockdown and canceled flights is helpful. 
 
As are proof that you maintained your residency. 2019 tax return. USA drivers license. Proof of payment of rent / mortgage, etc.  
 
If CBP concludes you intended to abandon residency you will be pressured to sign a document that says you abandon your residency.  
 
Sign nothing other than your customs declaration. Hold fast and eventually you will be admitted.  Worst that will happen is that CBP will recommend to DHS that you have a trial with an immigration judge to decide whether you abandoned your residency.  
 
That is the 6 month rule. Then there is the 12 month rule.  Your experience will be the same just even more pressure and more proof demanded. In the end though you have to be admitted.
 
The difference between the 6 and 12 month rules is that even CBP decides you did not abandon residency, it must still report this to DHS. And so for the rest of your life as a green card holder you will have the risk of an immigration trial.  The remedy is to naturalize. And you will have to wait 5 years for that (or 3 years if filing on the basis of a green card through marriage to an LPR or USA citizen).  
 
There are documented cases of people who were gone for years and entered the USA with no problems besides the expected secondary.  
 
How many months are left on your green card?

I am sorry to hear your situation. Although I am in USA on GC, I am worried to leave the country fear if your situation occurs to me. I would immediately contact local USA embassy in Phillipines immediately and explain the situation to see if they give you waivers. Also, to get some level of advice, you can post your question on this site and see what lawyers think.

Yes... Here is what Embassy is doing for India to move both US Citizens and Permanent residents to USA using special flights. Obviously, Phillipines would have its own situation.

Always best to verify anything a friend says, read on a third party website or is heard via any grapevine.  Tremendous amount of misinformation out there. 

They were mistaken. Being abroad over 6 months (but under a year) might raise some questions, but I would not expect an issue being let back in. The main issue is people who are consistently living abroad and just "touch down" in the US to avoid the 1+ year issue.
A trip abroad of 6+ months has a presumption of abandoning continuous residency for naturalization purposes, so in general it will delay the timeline to become a US citizen.

Thanks for the response. We already rebooked our International flight to April 17,2020. But until now there is no domestic flight. 

As noted, contact the embassy to make them aware of your situation. They can coordinate the next steps.

Sweeper flight occurred today 

A single trip of 6+ months but under a year is unlikely to be an issue here IMO.
There are repatriation flights as well, which I believe includes LPRs.

Save all your records, flight changes, cancellation notices etc.
 
   Just in case you need it, it's best to have proof that you intended to return to the USA but were unable to.  
 
   
 
  

There has been a lot in the news about rescue flights, make sure the Embassy know your situation so you are notified.

no one can see the future to predict that. you will need to contact the embassy when everything opens back up.

Green Card holders can stay outside the US for up to 12 months  without presumption of abandonment of resident status.  On the subject of your son, if the visa expires, there are provisions in the law that allow the consulate to re-validate an expired visa with a new medical exam, fees, etc at the discretion of the consulate officer......but I would try to travel before expiration.
