People from different cultures do the Nikah in different ways e.g. in some tradition the bride is in one room and the groom in another. However I believe that the correct way is to have the bride and groom in the same room and facing each other. Now you are asking about Skype. I don’t think it is permissible to have a ‘Skype Nikah’ because fraud can take place. There will be problems identifying the bride and groom. By this way you are not marrying somebody that who true identity you are unaware of. Also what if this is a trick to get something e.g. money or visa. Another reason is that the Imam performing the Nikah should feel comfortable and the witnesses too. I would recommend waiting a bit longer and doing the Nikah face to face because I sure you don’t want to continue the marriage as an only online relationship.
