Thus, it is better to ensure that you apply for the pass after 14 days of receiving your second dose so that you can get your card as soon as possible and have a convenient stay and travel. Also, you need to make sure that you buy domestic travel insurance for further secured travel. It is also important that upon receiving the link, you download the pass and keep it safely in order to ensure convenience. In case you apply as soon as you receive the last dose, you would receive the pass once the 14 days period is over.
