FJ,
Of course you are !
Some places in the world you can join an ILS outside radar and controlled airspace. Many precision and non-precision approaches have an IAF which allows a "straight in" entry into the approach.
MSA, manoeuvre as required (in the sector if it has one) to join the approach, if cleared to do so in CTA, or as you desire OCTA, providing you know you position in the MSA.
