My Resident Alien Card,(photo showing ear) was issued 09/30/1983.
There is no expiry date on the front, (or back) of the card. How am I
supposed to know when to renew it, if there is no information
provided?

Hi oldscot,

I have good news for you! You do not need to renew your card if you
were at least 14 years old when your green card was issued.

USCIS
Q. Do I need to renew my Green Card if it was issued between 1979 and
1988 and does not have an expiration date?
A. "No. Green Cards issued between 1979 and 1988 do not have
expiration dates and do not need to be renewed at this time. INS will
develop an orderly plan for replacing these cards at a future time.
(Note: If you obtained your Green Card before your 14th birthday and
are now over 14, and your Green Card does not have an expiration date
on it, you will still need to get a new card. You will need to go to
your local INS District or Sub-Office?not an Application Support
Center?and File a Form I-90, ?Application to Replace Permanent
Resident Card.? However, you will not need to pay the $130 application
fee. You will only need to pay the $50 fingerprinting fee.)

I was glad to find this for you. If you have any questions, please
post a clarification request and wait for me to respond before
closing/rating my answer.

Thank you,
