Credit Card Lounge

I don’t have a credit card, but I really need one just to purchase plane tickets and other things I buy online and build credit. By the way, I’m over 25 and I have been paying my student loan on time each month for almost 5 years. I think I have fair/good credit. I am between jobs right now. I know that sounds bad, but I’ll be starting a new job in June. What should I put for my income on the application. Should I put my income last year or for my next job. Should I mark unemployed?

I’m confused as to why my ( 2 ) credit card applications was denied. my only 1 credit card are regularly paid off.
I just check my FICO score is 707
I was denied online and they said they were going to send me an explanation why.

(I am an immigrant ) trying to build a good credit

My dad added me to the additional card for his credit card application. Will that help me build my credit since it asked for my SS# too?

I applied for Target, JCP, Sears, Wal-Mart, Macys and Sears they rejected my credit card application because I have No Credit history?! I think, No credit is much better than Bad credit!!!!

What can I do in this case? I need to build up my credit history.
Please advice.
