Seeking knowledge of Islam and Ahlul Bayt (a.s.) is the most valuable thing one is able to do. It is a long-term investment in which not only you will benefit from, but so will those around you.
You do not necessarily need to travel to Qom or Najaf to learn the important sciences of Islam, unless of course you wish to become a cleric or a qualified religious scholar.
Along with your day job, or secular studies, you are also able to allocate time to study religion, but just make sure you are following a syllabus and have correct guidance from a fellow Hawzah graduate. I am sure you will be able to find someone local, and in your language as well.
I have put together a Facebook page that shares useful information regarding Hawzah, and initial stages that can be taken to pursue Hawzah studies, even from a distance.
I also have a 10 episode program on my Youtube channel on this topic.
In shaa Allah you will be able to pursue your interest in Islamic studies, in any level it may be.
With prayers for your success.
