My xray result states that fibrohazed infiltrates in the left upper lung that results ptb. what does it mean? is this curable immediately? can it affect my application abroad?

The wording suggests you have lung changes from a prior episode of Tuberculosis. Further study would be required to decide whether the condition is still active and what treatment is needed. If this condition is verified, it is curable, but treatment may take time. The effect this has on visa applications and employability would vary with the disease activity level.
