A strange question that sprung to mind. Let's say somebody traveled to USA from another country and immigration wanted to see proof of their ties to back home...
The alien presents pay slips, job contract etc. but also provides a return ticket which is international first class. Would the cost of the ticket play a factor in the border officer's decision to allow/refuse the alien entry? My thinking was that an intending immigrant would be less likely to pay for a return first class for a few thousand if he did not intend to use the return ticket.
I ask because I was collating my documents for a future trip to the USA and I paid for an upgraded seat (premium economy lol) and this question sprung to mind and I thought it'd be interesting to see the responses.
