How is your English? You might want to consider that before you think about what field you want to go into. Some fields you’ll have to learn lots of new terms and if your English is not that fluent you’ll have to work on your English at the same time...... and learning another language takes a lot of time.
If you want to go into the Medical field, just make sure it is something you want to do. It’s really hard on you mentally looking after patients all day... If money is the only issue you are considering, then I would suggest the Medical Field in LAB WORK.
LPN and RN do mostly the same thing in a regular hospital. LPNs are not allowed to IVs. Otherwise the workload is very similar....... but because RNs are more qualified they get paid more.... So if you are considering it, you may want to look into RN instead of LPN. (This is what I heard from my experience as a nursing student in BC).
