My husband is finally a PR

My husband finally has gotten his PR. We applied in April 2014 after our ROM. And in Feb 2015, we finally gotten news. It took us about 10 months. Generally speaking, it is very fast already. There may be a couple of reasons that lead to that...

1) He is a Korean

2) He studied in Singapore before

3) We appealed through MP

4) I had a stable job to be a sponsor. 

5) He is a guy who has done NS

It was great that he has gotten his PR as he wasn't able to change his job despite hating it due to its really harsh long working hours. The Employment Pass (EP) he was holding on to was tied to the company and if he quit, he may have to leave Singapore if he couldn't find a job in time. 

Now that he has gotten his PR, he has quit his job and serving his 2 months notice period. We planned to go for a 1 month tour before starting my new job.
