Dear User, it depends on the underlying disease that is giving nephrotic syndrome. In fact, there are diseases, as FSGS, that only raraly goes to remission with zero proteiuria. On the other hand, diseases like membranous nephropathy may be in immunologic remission six months before the disappearance of proteinuria. Conversely, you may see MCD in complete remission after two week on corticosteroids. In general, although total 24h proteinuria is important, what really matters is the disappearance of nephrotic syndrome (serum albumin should be normal).
