GCMS notes are not helpful in the first 3 months as until that stage only the R10 is complete. No one can stop you from ordering it, but is does not provide you with much information. The processing time is 6 months, and be patient and let your file move at its pace. If there is not much movement, order the GMCS notes in the fourth month.
GCMS plays a vital role and should be used strategically. Although you can order the GCMS any number of times, but beware that each time you order the GCMS notes an agent is forced to open your file and review the notes before sending them to you. After the first four months files get staggered and some even though might have everything ready to move to the next step, but have been waiting for an agent to look into it. This is when the GCMS is of great use. Not only you get to see your file, when you request it, the agent opens it and will move it ahead if there is something waiting just to be entered.
The GCMS notes are most useful in the following scenario:
1. Medical showing not passed - In some cases the results are in, but an agent has not updated your file. If you request the GCMS an agent will be forced to open your file and while he is in it, he will update the medicals as passed.
2. BGC not started.
Every time you order GCMS, which is your right, you are also putting an extra burden on the CIC. So be mindful of when you order the notes.
In my opinion you should not order the notes in the first 4 months.
