What is the time limit to do social security

If you join the job this month and apply for social security on the 20th or so of this month, then it takes effect the following month. Generally everywhere in the time to handle social security regulations may not be the same. Some places can be changed in the month (such as additions, reductions), changes in the month, that is, the month for the same month, the same month to pay, but there is a time limit, such as the 25th can not be changed; some places are required to apply for a month in advance of the change, that is, this month for the next month, the next month to pay. So, either pay the fee in the month, or pay the fee next month, under normal circumstances there is no next month to make up the payment, unless it is because of the human operation caused by the month should be paid but did not pay, only to make up the payment.
