To apply or not?

Uncle Chris asked me to apply for this job in HK...should i? I'm getting married end of the year and potentially CS will be moving to his new job in Aug if everything goes well... what if i get the job? But actually i dont think i'll get because i really have no basis to apply for it...no experience at all how to apply for this band 5 job... some more its in HK?
Dilemma...dilemma...We have been thinking of relocating but where is the best place to work with the market condition like now? What can we do there...as in both of us? What's the opportunity? When is the time we can leave things behind and move to somewhere?
We are so attached to the things here...
1. Family
2. Fifi/lexus
3. Friends (why friends is number 3 behind our dogs? Are they not precious enough? Actually not but they can be connected online...they can visit us... we can come back...we can chat over the phone but our 2 doggies can't do all the above... that's why!!)
Sigh... sigh...sigh...
