SLR Permanent Residency Question

Hello everyone, I’m a future UC Berkeley student but before any of that happens, I’ve come upon quite a troubling situation, I am a permanent resident of the U.S. and so I must put Permanent resident in my Statement of legal residence, but the thing is that my green card expired on the 25th of April. However, 2 months ago we went to process a renewal; they extended it until March 2019 until I receive my new card. What do I put under card expiration date? Do I just put 4/25/18 as shown in my current card and let them process the fact that it’s been extended? or should I but March 2019? (only problem being that there’s no specific day, only month and year) Any help is appreciated, thanks!

Put the date it has been extended to. If they want any further clarification, they will probably ask to see the card with the extension.
