Family visa

Hi I am still in th U.K and not sure if my family will be moving to Jeddah with me.
However this may change once I get there if I feel it's suitable for them.

Should I get their visas done now or once I'm there. I must complete a 3 month probation aswell.

Be patient...Let your probation be over plus you need to know what your profession is on your iqama to apply for a family visa...
