i am travelling on a south african passport to india and am aware of the fact of obtaining a visa before i go but i need to know if i must request a multiple entry visa if i want to go on to nepal? or is does the visa allow for this. also is it fine to use my debit card? travellers cheques the way to go? and where can they be cashed? Should they be in rupees or dollars rather?American express or thomas cook?i thought travellers cheques were a thing of the past mostly..
