I Just wanted to mention that when i applied to sponsor my husband, at that time I was not working, I have worked in the past before (part time jobs) but while I was sponsoring my husband I did not have any job and I did select unemployed on my forms when I was filling them out. My reason was that I am a full time student and so I needed to focus on my studies, I got approved as a sponsor in less then 30 days....It was because I had filled out my taxes in the previous year and in my option C printout it showed an income, even if it wasn't a lot.
So, therefore, no you dont have to be working throughout the sponsorship process to prove anything, once you are approved you are approved...although yasmeen may be right about them asking for an employment letter if your staying with your spouse abroad, other then that I cant think of any reason why they would ask for proof again because we all already got approved as sisters.
But I totally see where you are coming from Yasmeen sister, if i had a good job with a good salary then I would be hesitant to quit too, as we will need the money plus you can buy things for your home for when your hubby comes! (i already bought few things
) The only reason why I quit my job because it was a *censored word*ty part time job with minimum wage and I really did need more time for my studies
