hello satyam

as per my own personal experience mai aapse bol rha hu . aapko character certificate update karwana pdega ya new bhi banwa sakte ho . migration certificate update karwane ki zarurat nhi hai . ek aur bat usually colleges documents submit krne ke liye proper time dete hain . mjhe gap year certificate ki zarurat nhi pdi thi .

aap thoda aur research karlo because ye sab mai personal exp ke basis pe bol rha hu and things might change a bit ,so there is no harm in taking precautions

best wishes
