manage to settle everything. overall, i still consider the whole process to be rather smooth although there are quite a number of wasted journey to ICA and some unnecessary spending. still there is no way i can know everything before going through the whole process anyway
for those that is going to or applying PR for your love ones, good luck
the whole thing took 6months although much longer if consider the time taken to prepare all the documents especially back in her mother land where the process is complicated and lengthy.
