I forwarded mine to Google Drive before I left the United States seven years ago. It still works. It seems like you can’t get a drive unless you’re in the United States to store it though. When people call it, they get a message that says say your name, and then it puts them through and ask if you want to receive a call from John, etc.
I lost track of the OP country, but I would not take large amount of cash to the United States. They can take it under civil forfeiture , claim you are a drug dealer or or money launderer and you are unlikely to get it back. Many stories about this. 
and make absolutely sure when you present your passport at the airport, to say this is on a reentry permit. Turn your passport to that page, even they will take it back to the first page. Look him/her straight in the eye, because often when they’re bored and tired and will start to automatically stamp you in for 30 days instead. check your passport stamp before you leave the area. 
If your girlfriend is applying for a tourist visa and she mentions you, a US citizen, having relationship with her, she absolutely won’t get the visa. The reason is that you could go together with her as a tourist, and the two of you could happen to decide to get married, and she would have the right to adjust status and get a green card. They don’t want that, they want you to get the fiancé visa and do consular processing. If she doesn’t speak of the relationship with you and says she’s going to tourist places, they’re unlikely to believe her. If she has the history of travel to other places, such as Europe, a house, car, and a long-term corporate or government job, she may have a chance. As someone else said, it sometimes take a second or third attempt, and it can take a year to get the interview.
