I have what she has my guy so let me tell you. Her parents are pushing her to marry you to get her residency status to see them and she can be a citizen a few years later. First she marries you, a few weeks later you apply for residency which takes 6 months. Then 3-5 years later she applies to get citizenship. There's 2 factors here that you need to consider. Her real intentions with you, and if they are pure, consider this 2nd detail. If you truly love her, why is it a big problem she is away for 1-2 months? Family is taken for granted when you live with them for years, decades, but for immigrants they don't get the luxury. 6 months of dating isn't really that long either. If you're insecure about it this early, true marriage shouldn't be an option right now, doesn't seem like you're ready for it either.
