I applied for Mother super visa my time line is as follows.
Application received CHC Islamabad on January 27, 2012
Got Medical request on March 13, 2012
Completed medical and sent back passport on March 14, 2012
On April 23, 2012 got a letter from CHC New Dehli dated April 09, 2012 for another X-ray called Lordotic X-ray.
Got appoint from same doctor for 2nd X-ray for April 26, 2012.
Can any one shed light if he or she gone through 2nd medical request?
I will keep posting further update so that some one else might get help if he is in same situation.
One more thing worth to mention that CHC New Dehli sent 2nd medical request through normal post (no courier) that's why it took almost 13 days to get this letter.
