Thanks!
No, from my Salary of July-December 2019, I won't meet LICO.
In the meanwhile, can I get them a normal visitor's visa? Will that be approved, in your opinion?
TRV is dependent on your parents savings, ties to their home country and international travel history to countries like Australia, US, UK, etc. Hard to comment on whether they will be approved. Given that you haven’t earned above the LICO amount a TRV is your best option for your parents to visit.
