USA English. Your question is a good one. Filling out the immigration forms properly is important. Failure to submit forms with the proper answers or replies is the main cause for failure to receive approval.

The skin is composed of two layers: the epidermis and the dermis. Underneath these layers lies the hypodermis. The epidermis is stratified squamous epithelium. The dermis is composed of a papillary layer and a reticular layer. The reticular layer of the dermis is made up of dense irregular connective tissue.
Persons with thin skin have a thin epidermis. The subcutaneous layer, the third layer of skin, is located beneath the dermis and consists of areolar (minute spaces in tissue) and adipose (fat) tissues. The first skin layer is fixed to the second skin layer as though the two were glued together. The second and third skin layers are attached in a different way. Fibers from the second layer (the dermis) extend down into the third layer (subcutaneous), anchoring the two layers together.
