please advise

oh you mean the sikhni's work visa expired ???.... can you reply and confirm this.

wow if thats the case , then there's the motive... issi liay tau cousin ke husband ko pataya hei usnay... the sikhni is just using your cousin's husband to immigrate to UK, and has no intentions of being a good muslim.. your cousin's husband is a stupid stupid stupid man, for falling in her trap, and actually thinking this sikhni loves him, and he loves her...
he will suffer for his stupidity
if its in UK try to scare your cousin's husband off, saying he is not legally allowed to have a second wife...if he doesn't hear, then your cousin can take legal action and tell the UK government about his crime (of marrying two women) the legal consequences will teach him a lesson!
