8 year delay for adjustment of status is not "unreasonable" according to the 8th Circuit

"Given the facts specific to Debba that have caused the delay, and
assuming for purposes of our analysis that there is a judicially-enforceable
“reasonable time” requirement, we conclude the delay in processing Debba’s AOS
application was not unreasonable."
