Alien Registration Card (ARC) not written on passport

[gc_wait_485]

Upon the entry, officers write 'ARC' on the passport stamp, but, at this time, he didn't.
Is there any issue not having 'ARC' on the stamp?

No, just as there is no issue if your passport isn't stamped. Did you show your GC?

Yes, I showed my GC.
