Hi, I have recently sponsored my Fiance on a Tourist Visa Subclass600, we used a Migration Agent that were absolutely useless dealing with our application but after a frustrating 10 months the Visa was approved and she spent 3 months here. We are now wanting to submit a Prospective Marriage Visa Subclass300 but now want to deal with a different Migration Agent. Does the Department of Immigration or Embassy contact our previous Agent for any reason? As we are concerned that they will make it difficult for us because they have expected us to use their services for the Subclass300. Any information would be appreciated.
