Hello,
Welcome to VMware communities!!!
You will get "Import from vSphere" opiton only if you login to vCloud home url (https://FQDN/cloud) and also as a system administrator.
Cano you go to Org, under Administration --> Cloud Resources --> Virtual Datacenter --> Click your datacenter and check the Org VDC is listing there.
Also click the Monitor tab and check if resources are available.
