UK visitor staying for 7 weeks. Some travel books say only a passport is required, others say visa or ETA is also required.

We are going to UK & Europe in Aug . My wife is a permanent resident of Australia with an Indian passport. What is the procedure to apply for Visa to UK /Europe?

I have applied for visit visa to UK. Can anyone advise me how many days it takes approx to get the visitor visa to UK applied from Australia.

i hold a student visa of uk and holding the indian passport.my question is can i visit the europe countries with this visa or i have to apply separate for visa for that particular country.
