Switching Rabbi

Dear Rabbi,

Firstly, a huge yeshar koach on this website; I feel you are providing an invaluable service to the Jewish community worldwide.

My question is as follows:

My city is blessed with multiple frum yeshivos, each with a slightly different hashkafa.

I am currently in my final year of a 4-year post high school Bais Medrash program. I would like to know whether:

Once I complete my program, I’m allowed to switch to a different rav in the city for general and specific guidance in life—a rav who has a generally more liberal hashkafa (but is still solidly within the Torah framework).
And if so, do I need to obtain my current rav’s (Rosh Yeshiva’s) permission?

(Reason for my question: When I enrolled in my Bais Medrash program, I wasn’t aware at the time how “right wing” and strict the yeshiva was compared to most other yeshivas in my city. Just to cite an example: The hashkafa of my Rosh Yeshiva is that bochurim should ONLY look for a wife who can financially support their full-time Torah learning. I, on the other hand, don’t want to restrict my options. As much as I love learning, I also have other interests/passions and I don’t see the harm in starting my own business, for example, while learning a bit in the mornings and a bit at night. Another example is regarding the use of the internet; my Rosh Yeshiva, in my view, is overly strict in his approach)

Thank you!

ps. On a totally unrelated matter, I noticed that on this template there is a error that you may want to fix: “Do you need a video to description the problem better ?” Should be “to describe”.
