Thanks for the suggestion.I would be concerned to apply based on the kids as should your ex get full custody I don't know what the situation would be, and divorces have a nasty habit of turning nasty. If you have a job, is it not possible to get your PR based on that or your period of staying in RSA?
LegalManwould be best to advise on this.
I'm sure there will be some disagreements when it comes to sorting things out. If she got full custody I would be absolutely gutted. But I see your point.
I see there is Direct Residency.
'...applicable to foreigners who have been residing in South Africa on the basis of their work permits for a minimum period of five years...'
I've been here 6 years. Though this is based on those with a Work Permit. Its a technicality but I did my time on a Relative's Permit to get PR.
As you say I'm sure LegalMan will have some thoughts on this too...
