I am Married to a Portuguese woman since 2007, but we live in Asia - Near East. Do i have the right to get the Portuguese Nationality? And how?
You should be entitled to Portuguese nationality. The best thing to do is to check with the nearest Portuguese consulate to know what you have to do to apply.
Yes, although the marriage must have lasted for more than 3 years (Portugal also accept common law marriages/civil unions), which yours obviously have. It also needs to be registered in the Portuguese system.
There’s more information here: http://www.embassyportugal-us.org/through-marriage/
I would follow @vepareto’s advice: Contact the nearest Portuguese embassy or consulate and take it from there.
