In case anyone is not sure about what possible questions an immigration officer could ask your spouse on arrival at the airport.
The following were some of the questions my wife was asked.
1) Which colour are your husbands eyes?
2) Do you have a copy of your husband's passport?
3) What is your husband's full name, age and date of birth?
4) Do you have your marriage certificate with you? My wife had a copy and the officer said its fine.
5) When did you get married?
6) Which address are you going to be living at?
7) What is the purpose of your visit/type of visa
How long is your visa valid for etc. 9) Where is your husband at the moment?
10) Can I see your TB test certificate.
I was quite shocked at the amount of questions that were asked.
