FIL has been enticing hubs' sister and her husband to take up a Nursing course at his expense so they can later look for a job abroad. Many friends and relatives are encouraging them too and promising to hook them up with CNA schools in their area where SIL and BIL can take up CNA courses or additional requirements.
She could atually just take up a two-year course in practical nursing because she's already a college grad.
CNA training is also very easily had since there are many CNA schools offering them. This means that if SIL and her family wants it, they can really easily land jobs where there is much opportunity for career advancement, and where they can enjoy security of tenure. But SIL hasn't decided yet so she hasn't enrolled yet.
