I am trying to travel to visit my ill dad but don't have the money to do so and it's killing me. I work hard and pay bills and i am a productive abiding citizen. i have a good credit score, etc.. Can someone go to the bank and ask for cash as in loan and then pay them monthly for it? how do some one go about to do that? I am only in need of $3,000

Most banks have online loan application but it appears you need to see the loan officer in person. Go to your bank, ask to speak with a loan officer, and conduct the transaction. If you don't use a bank then a secondary online source would be the best bet but you'll also pay higher interest rate.

Yes - one can - it is called a personal loan. Note that the interest rates on personal loans tend to be higher because there is no collateral. Also, because there is no collateral, they are also harder to get. Best you can do is fill out an application at your bank and try.

Yes its possible to get a loan at your bank a lot of people that start businesses do it , you just have to be able to pay them back

Yes, you can get a loan at your bank !
