My parents travelling recently after the rule changed. Some pointers.
1. At Indian airport they asked for Credit/Debit card. My parents showed their debit card. Done.
2. At Qatar Airport, immigration officer asked where would they stay. My parents replied with son/daughter in law and the area/city in Qatar. Done.
3. Visa stamp was giving for 30 days.

No credit card required, no hotel reservation required. But visa for only 30 days.
