Here are couple of advice for girls - foreigners who is wishing to marry Indian guys:
1. Marriage in India is very serious step and without parents no one guy will never do it by himself.
2. Marrying an Indian guy, you getting married to all his family, traditions, manners, and so called vox populi. You can never avoid this things.
3. whatever people say, 99% Indian guys marry only Indian girls always. This is the reality and you can`t change it.
One of my Indian friends (we know each other more 25 years) is not married because of some matters. We are very good friends, so we can share everything between us. So, once he told me - If i could get married, she would be an Indian girl only. And this despite the fact that 10 years he has studied and lived in USSR and knows different lifestyle. The second one is divorced and has a daughter with his ex-wife, but he says, that if i get married once again, girl should be single and without kids. How you like it?
Now make a conclusion and think thrice.
All the best.
