Hi again, sorry need more questions to be answered..more help the better

Is it possible for my husband to include on his letter of support who is paying for the flight and the visa fee?or should we not include it? his parents wanted to pay for it as their gift to us and help as well since they do not want us to touch the savings we have. What are the chances that the embassy will refuse my visa for that? or will they?! My husband has a regular full time job in call center and not much of outgoing expenses but was not able to save much on his bank when he sends me money over. He has also savings. We are thinking to include a letter of support from his parents in order to show the embassy that the savings we have will be untouch.

looking forward for answers and more help
