How long is the minimum stay at Amritapuri, and how do you apply?

Amritapuri's official pages don't give a minimum stay. They say everyone is welcome to stay at any time and take part in daily activities. International visitors, including OCI holders, should register online before arriving. Indian visitors should email [email protected] or call +91-70340-24286. Groups of six or more should give at least 7 days' notice. Bring ID: Indian visitors need Aadhaar or a voter ID, and foreign visitors need a passport plus copies of the passport and visa. Single men and women stay in dormitories. Amma travels often and doesn't give darshan on Tuesdays or Fridays, so check her schedule before you go.
