Only those of high social status or wealth were granted citizenship, along with their children.

Initially, but not during Rome's decline. https://old.reddit.com/r/RoughRomanMemes/comments/p1szoo/mohammad_is_a_chad/h8idujm/ And what about those who acquired citizenship by means of auxiliary service?

Exceptions were made for Alexandrians, who were the only Egyptians who could become citizens. Only separatist races (Egyptians, Jews) were looked upon by Romans with increasing suspicion. Exceptions were also made for blacks who distinguished themselves, such as Septimius Severus.
