My point of view

1) Put your papper only after getting to Visa

2) if you are friendly with current company HR or HOD please tell them the truth

3) if your visa application is rejected (not normaly happens) and you submitted your resignation letter , you may loose existing job also

4) check the following

do you will get any F&Fs benefit from your existing company- if not puit down your papper at any time and grab the golden opportunity

if yes, there should be an option for early resign, by paying proportionate Basic salary to the company

please check
