The following is my doctorate level research proposal

Title: "The Effects of Migration on Nigerian Children Who Migrated with their Parents to the United Kingdom: An In-depth Qualitative Analysis."

Brief Research Background
The migration of parents from developing to developed countries has become increasingly common in recent years (Suárez-Orozco & Suárez-Orozco, 2015). As a result, millions of children are affected by the migration of their parents, including those from Nigeria (UNICEF, 2019). The phenomenon of parental migration has significant economic, social, and psychological effects on children, particularly those who migrate with their parents (Capps et al., 2004). When parents migrate to a country such as the United Kingdom, where the cost of living is high and access to resources is limited, it can have even greater implications for their children (Akhigbe & Effevottu, 2023). Nigerian migrants make up a significant proportion of the immigrant population in the UK (Office for National Statistics, 2020). However, despite the growing number of Nigerian migrants in the UK, little is known about the effects of parental migration on their children who have migrated with them. Previous research on migration and children has mostly focused on children left behind in the country of origin, rather than those who migrate with their parents (Skrbiš, Baldassar, & Poynting, 2007). Therefore, there is a need for an in-depth qualitative analysis of the experiences of Nigerian children who migrate with their parents to the UK and the effects of parental migration on their lives.
Aims:
This research aims to explore the effects of migration on Nigerian children who migrated with their parents to the United Kingdom. The study will specifically investigate the social, economic, and psychological impacts of migration on the children.
Research Questions
The research questions that this thesis aims to answer are as follows:
1. What are the impacts of migration to the UK on Nigerians/sub-Saharan Africa.
2. How do people overcome the challenges posed by migration?
(because we don’t know how much literature is available that focuses on Nigeria).
3. How does gender influence the challenges Nigerian migrants face in the UK?


Methodology
The research methodology is grounded in established research practices and has been used in previous studies on the economic impacts of parental migration on children (e.g., Lu, Yeung, & Treiman, (2020); Fellmeth, et al., (2018)). This study will use an in-depth qualitative approach to explore the impacts of migration on Nigerian children who migrated with their parents to the United Kingdom. The sample will consist of Nigerian families who migrated to the United Kingdom in the last five years with children between the ages of 6 and 18 years old. Data will be collected through semi-structured interviews with parents and children (Creswell & Creswell, 2017). The interviews will be audio-recorded, transcribed, and analyzed thematically (Braun & Clarke, 2014).



For the dissetation, I am to do a comprehensive 4000-word literature review of a substantial portion of literature related to the focus area
Give me a comprehensive and detailed structure (including word-count) to get this done in the best way possible
