There have been delays due to covid but delays can also come from the details of the application. If there was less than 6 months left on a study permit spouses OWP are not usually approved. Although not SOWP the TRV application may be viewed the same as the OWP. The TRV will be viewed differently if the spouse is finishing her studies, has just graduated and is looking for employment and PGWP approval or has been granted PGWP and has a job in NOC 0, A or B with 3 pay stubs.
@gomez999 I would suggest applying for GCMS notes for more information on your file.
