Q: Can I accept to take some of my wifes savings to bear all the visa expenses including residense, rent, etc. this year? I am married since 2 years. Me and my wife do job. She is a teacher in homeland. While I work abroad (middle east). I give pocket money to my wife every month, as well as food expense separately to my joint family. I get one month leave to visit my family in a year. Two times I brought my wife on visit visa in two years. This year I have plan to save some money and to buy some property in my homeland in future, hence not to invite my wife this time, but she agreed to pay all expenses on her own, which I didn't agree. As I don't feel comfortable to get any of her earnings, because of her talking many times that she strongly feels that, her earning is totally for her. On the other hand she taunts me many times that I don't save enough money to get some property. What should I do?
