It simply means that, if you had left your Filipino family and PH before or after 0001H March 22, 2021, you must wait until after 2359H April 21, 2021 to be able to reenter PH, if you have a valid visa. Should an emergency situation occur in your Filipino family that requires your immediate return to PH before2359H April 21, 2021, then you may write a request for humanitarian consideration to the NTF COVID-19 Chairperson or his duly authorized representative pursuant to Rule B.1.b.v of IATF Resolution No. 103 (March 18, 2021). This option has also been made known thru the media. By the way, Philippine Air Lines sought clarification and it was confirmed that only the foreign spouse of a Filipino citizen whose marriage is in accordance with provisions of the Family Code of the Philippines shall be allowed entry as an exception. Further, foreign adopted child/ren of Filipino citizens are included among the exception. There is really no need to try to fathom out or make sense of any country's rules if you are not its citizen. In the same way that Our Maker's thoughts and ways are higher than that of all peoples', so are governing authorities' policy thoughts and ways higher than that of constituents'. Either you follow the rule or you do not follow it.
