How can I place a pokestop

How can I place a pokestop…Iam a 35 level player but I got a option to add a pokestop but after visiting the website and signin there is only review option…and how much I need to review to get eligible for applying for a pokestop…

You submit a Wayspot from within Pokémon GO.

Settings > Uploads > New PokéStop

Be aware you’re actually submitting a Wayspot which can become a PokéStop if it meets Pokémon GO’s inclusion rules.
