Our analysis starts with the study of horizon structure for the BH spacetime in $f(Q,\\mathcal{B})$ gravity. The strong field lensing analysis is done by employing the method developed by V.~Booza. We calculate the deflection angle for the static and spherically symmetric $f(Q,\\mathcal{B})$ gravity BH spacetime and compare the results with the Schwarzschild BH.
