Sorry, yes he is losing his visa and I am departing with him.
So whats your plan? Will he be applying for a British visa from his country, and you both will stay there until he gets it or? Is it even possible for him to get a visa easily or could there be complications?
I'm asking these questions, because it might be better to look at this situation from another angle. The way you asked the question, its a bit muddled and therefore the chart will be unclear too. You need to ask a question that can be easily answered with a yes or no and a timeframe. A better question would be 'will I return within the next 6 months?' Or will my bf get his visa this year? etc
Looking at this chart, Mercury can be the visa or some type of paperwork. Saturn can be the government... (Immigration department). I could take Mars as both you and your partner, because you are a couple and you are waiting for visa and travelling together. Mercury applying to Mars might mean getting the necessary documents. Moon here is Void until it gets to Sun. So again a period of waiting.
Saturn is the Immigration department, and 11th (2nd from 10th) documents issued by them, again Saturn. 5th is for ambassador, and 6th (2nd from 5th) the paperwork they issue. Look how both Mercury (documents) and Sun (Moon's next aspect) are in the 6th. To me it looks like you going to the British Embassy in SA and from there on starting the process of visa or perhaps having to deal with them there.
Mercury is strong and so is Sun, so I think visa will be there but might take some time.
