| Year restrictions | Many universities do not allow free mover mobility in the first year of a bachelor's or the final semester of a bachelor's or master's | Time your application for a middle semester |
| Faculty-specific restrictions | Medicine, law and other highly regulated programs often face formal barriers, because no external exams are recognized by default | Investigate early with your department coordinator, not the general international office |
| Quotas per destination | Some universities limit how many students can attend the same institution in a given semester | Choose another destination: the experience at a comparable institution is rarely diminished |
| Prestige and accreditation | Some will not sign off on mobility to unaccredited or low-recognition institutions | Show them the institution's accreditation credentials |
| Partner university conflicts | A bilateral agreement, such as Erasmus, with your destination may stop you from going as a free mover | Choose a destination outside their existing partnership network |
| Internal outgoing deadlines | Your university may close approval for outgoing mobility before the host deadline | Check for an internal outgoing deadline before you plan your timeline |
