Help My Mother Meet Her Grandaughter

Hey guys. In April last year, i started speaking to a lady in Kentucky. I lived in Australia. We grew close, and started dating online. After 5 months of dating online, i flew over to America, married Brittney, and we are living together happily :) I adore her 3 children. and as a family, we are growing. We are now expecting a baby girl in August, and very excited. As i am transitioning from Australia to America, and have a residency application in process, i am not allowed to leave the country, as that is considered as abandoning my application, I would like to raise some funding for my mother (who still lives in Australia) to fly over here, and stay for a couple weeks so she can meet her granddaughter and be here for the birth. It would also be a great time for my mother, and mother and father in law to meet, and also for my wife to meet her mother in law. My mum works really hard, But has a lot of bills to pay and simply cannot afford to pay for the trip. As i so not have any form of income either, it is nigh on impossible for me to get money together to help also. I really dont like asking for handouts., but i really would love all the help i could get to help my mother come over to America and meet her granddaughter, it would mean so much to me, my wife, and my mother for this to be able to happen. Thankyou in advance for all help, you have no idea how appreciative we would all be. Also, as a side note, we will be putting a little money aside to hopefully add to the cause. Once again, thankyou
