If you have 30 hours in last 36 months, then you can submit your application not before 3 months from the expiration date of your current RTR, if you dont have those 30 hours, then you should go ahead and fill up the form for RTR PART 1 Only exam, clear it and you will have 2 options (5000 for 20 years and 10,000 for lifetime)...... hope this helps...good luck
