I got a nexus letter from a well-respected company and have Disability Benefits Questionnaires (DBQs) completed by the medical professionals from my nexus evaluation. Would it be more beneficial to submit these documents online to support my claim or to bring them to my Compensation and Pension (C&P) exam? Moreover, I'm applying for an increase in my rating for obstructive sleep apnea, currently at 0 percent. Could anyone share what to expect from this upcoming appointment? Thank you all for your support.
