No it shouldn't. They don't care about cultures and customs so long as you can establish a strong relationship to your spouse. I.e. Via letters from family and friends, lots of post wedding, wedding and pre wedding pictures and lots of communication proof. My husband and I didn't have a traditional wedding there were no rasams done because I don't follow any of that. I know people who didn't even do valima and got their pr in less than a year. So just focus on showing a strong bond to your wife, and commitment to your marriage and her.
