The time limit for degree completion is usually set by the university itself. This timeframe varies widely depending on the institution, the program (e.g., a 4-year bachelor's degree vs. a 6-year medical degree), and sometimes even the individual student's circumstances. Common time limits range from 4-7 years for undergraduate degrees, though some universities may have longer maximum timeframes or may offer extensions on a case-by-case basis due to extenuating circumstances (e.g., illness, family emergency).
If you're concerned about the time limit for your degree, you need to contact your university's registrar's office or your academic advisor. They'll have the specific rules and policies relevant to your situation and program.
