Has anyone gone through the process before?

From the research I have done, the first step is to send off logbooks to be examined by ASL who will write back with a letter describing the steps to continue. For someone working as a 121 pilot in the US currently it sounds like they will respond by saying take the ATPL Air Law exam, get a class 1 medical and take the ATPL flight test.

Does this sound right? If so, I had also seen somewhere that it can take 4-6 weeks for the logbooks to be verified for cross crediting towards the ATPL.

Thanks
